Install Multiple Agents on the Same Machine

TeamCity treats equally all agents no matter if they are installed on the same or on different machines. However, before installing several TeamCity build agents on the same machine, please consider the following:

• Builds running on such agents should not conflict by any resource (common disk directories, OS processes, OS temp directories).
• Depending on the hardware and the builds you may experience degraded builds' performance. Ensure there are no disk, memory, or CPU bottlenecks when several builds are run at the same time.

After having one agent installed, you can install additional agent by following the regular installation procedure, but make sure that:

• The agents are installed in the separate directories.
• They have distinctive work and temp directories.
• Values for name and ownPort properties of buildAgent.properties are unique.

If you are installing additional agents as services under Windows, modify the <agent>\launcher\conf\wrapper.conf: wrapper.console.title, wrapper.ntservice.name, wrapper.ntservice.displayname and wrapper.ntservice.description properties should have unique values within the computer.

Moreover, make sure you don't have build configurations with absolute checkout directory specified (alternatively, make sure such build configurations have "clean checkout" option enabled and they cannot be run in parallel).

Watch Several TeamCity Servers with Windows Tray Notifier

TeamCity Tray Notifier is used normally to watch builds and receive notifications from a single TeamCity server. However, if you have more than one TeamCity server and want to monitor them with Windows Tray Notifier simultaneously, you need to start a separate instance of Tray Notifier for each of the servers from the command line with the /allowMultiple option:

• From the TeamCity Tray Notifier installation folder (by default, it's C:\Program Files\JetBrains\TeamCity run the following command:

  Code Block
  JetBrains.TrayNotifier.exe /allowMultiple

  Optionally, for each of the Tray Notifier instances you can explicitly specify the URL of the server to connect using the /server option. Otherwise, for each further tray notifier instance you will need to log out and change server's URL via UI.

  Code Block
  JetBrains.TrayNotifier.exe /allowMultiple /server:http://myTeamCityServer

See also details in the issue tracker.

Move TeamCity Installation to a New Machine

If you need to move existing TeamCity installation to a new hardware or clean OS, it is recommended to follow instructions on copying the server from one machine to another and then switch from the old server to a new one. If you are sure you do not need the old server data you can probably perform move operations instead of copying.

You can use existing license keys when you move the server from one machine to another (as long as there are no two servers running at the same time). As license keys are stored under <TeamCity Data Directory>, you transfer the license keys with all the other TeamCity settings data.

A usual advice is not to combine TeamCity update with any other actions like environment or hardware changes and perform the changes one at a time so that if something goes wrong the cause can be easily tracked.

Generally it is recommended to use a domain name to access the server (in agent configuration and when users access TeamCity web UI). This way you can update the DNS entry to make the address resolve to the IP address of the new server and after all cached DNS results expire, all clients will be automatically using the new server.

However, if you need to use another server address, you will need:

• Switch agents to new URL (requires updating serverUrl property in buildAgent.properties on each agent).
• Upon new server startup do not forget to update Server URL on Server configuration administration page.
• Notify all TeamCity users to use the new address

h3. Integrate with Wiki

You can use [external status widget|Enabling the Status Widget for Build Configurations] to incorporate information about a build status into any HTML page.

For example, to include the status widget into a Confluence page, ensure you have XXX plugin installed that will allow to include HTML snippets into any page and use markup like (do not forget to replace _<values>_:

{code}
{{include-html}}
<style type="text/css">
 @import" <TeamCity_server_URL>/css/status/externalStatus.css";
</style>
<script type="text/javascript" src="<TeamCity_server_URL>/externalStatus.html?js=1&buildTypeId=<buildConfigurationId1>&buildTypeId=<buildConfigurationId2>&buildTypeId=<buildConfigurationId3>">
</script>
{{include-html}}
{code}

...

TeamCity allows user to display information about current status of a build configuration on a Confluence Wiki page (as well as on any other web-page) [via the external status widget|Enabling the Status Widget for Build Configurations].

{note}Please beware that any information about build configuration published with the external status widget is available for *any* viewer of the page where you've integrated the widget.{note}

Please note that to integrate status widget into the Confluence page or another Wiki page you should have a macros or plugin which allows to insert plain HTML code into the page. For example, in Confluence you can use {{include-html}} macro.

Share the build number for builds in a chain build

Suppose you have build configurations A and B that you want to build in sync: use same sources and take the same build number.
Solution:

1. Create a build configuration C

...

1. , then snapshot dependencies: A on C and B on C.

...

2. Set the Build number format in A and B to:

   Code Block
   %dep.<btID>.system.build.number%

   Where <btID> is the internal ID of the build configuration C. Please refer to the Build Configuration page for description of how to determine build configuration ID.

More on Read more about dependency properties.

We plan to provide more option on build number sharing. Please watch/comment on TW-7745.

Use an external tool that my build relies on

Assume, to run a build If you need to use specific external tool to be installed on a build agent . To solve the problemto run your builds, you have the following options:

• Check in the tool into the version control and use relative paths.
• Create a separate build configuration with a single "fake" build which would contain required files as artifacts, then , use artifact dependencies to send files to the target build.
• Install and register the tool in TeamCity:
  1. Install the tool on all the agents that will run the build.
  2. Add env. or system. property into buildAgent.properties file (or add environment variable to the system).
  3. Add agent requirement for the property in the build configuration.
  4. Use the property in the build script.
• Add environment preparation stage into the build script to get the tool form elsewhere.

Install Multiple Agents on the Same Machine

If you want to install several TeamCity build agents on the same machine, please consider the following:

• TeamCity will work with the agents the same as if they are installed on different machines
• The agents builds running on the agents should not conflict by any resource (common disk directories, OS processes, OS temp directories)
• Depending on the hardware and the builds you may experience degraded builds performance. e.g. ensure there are no disk, memory, CPU bottlenecks when several builds are run at the same time.

For installation instructions, refer to Setting up and Running Additional Build Agents.

TeamCity Tray Notifier is used normally to watch builds and receive notifications from a single TeamCity server.

In situations, when you have more than one TeamCity server, and want to monitor them with Windows Tray Notifier simultaneously, you need to start a separate instance of Tray Notifier for each of the servers from the command line with the /allowMultiple option:

• navigate to TeamCity Tray notifier installation folder (by default, it's C:\Program Files\JetBrains\TeamCity and run the command:

  Code Block
  JetBrains.TrayNotifier.exe /allowMultiple

  Optionally, for each of the Tray Notifier instances you can specify explicitly the URL of the the server to connect to with the /server option. Otherwise, for each further tray notifier instance you will need to log out and change server's URL via UI.

  Code Block
  JetBrains.TrayNotifier.exe /allowMultiple /server:http://myTeamCityServer

See also details in the issue tracker.

Since TeamCity 5.1 there is an ability to delete many builds from the build queue in a single dialog.

Estimate hardware requirements for TeamCity

...

The agent hardware requirements are basically determined by the builds that are run. Running TeamCity agent software introduces requirement for additional CPU time (but it can usually be neglected comparing to the build process CPU requirements) and additional memory: about 150Mb. Although, you can run build agent on the same machine as the TeamCity server, the recommended approach is to use a separate machine (though, it may be virtual) for each build agent.

The server hardware requirements depend on the server load. The load on the server , which in its turn depends significantly on the type of the builds and server usage, so here are only some . Consider the following general guidelines.

Overview on the TeamCity hardware resources usage:

• CPU: TeamCity utilizes multiple cores of the CPU, so increasing number of cores makes sense.
• Memory: See a note on memory usage. Consider also that required memory may depend on the JVM used (32 bit or 64 bit).
• HDD/disk usage: This sums up from the temp directory usage (<TeamCity home>/temp and OS temp directory) and .BuildServer/system usage. Performance of the TeamCity server highly depends on the disk system performance. As TeamCity stores large amounts of data under .BuildServer/system (most notably, VCS caches and build results) it is important that the access to the disk is fast. (e.g. please pay attention to this if you plan to store the data directory on a network drive).
• Network: This mainly sums up from the traffic from VCS servers, to clients (web browsers, IDE, etc.) and to/from build agents (send sources, receive build results, logs and artifacts).

The load on the server depends on:

...

• number of build configurations;

...

• number of builds in the history;

...

• number of the builds running daily;

...

• amount of data generated by the builds (size of the build log, number and output size of unit tests, number of inspections and duplicates hits etc.);

...

• number of agents and their utilization percentage;

...

• number of users having TeamCity web pages open;

...

• number of users logged in from IDE plugin;

...

• number and type of VCS roots as well as checking for changes interval for the VCS roots. VCS checkout mode is relevant too: server checkout mode generates greater server load. Specific types of VCS also affect server load, but they can be roughly estimated based on native VCS client performance

...

• ;

...

• number of changes detected by TeamCity per day in all the VCS roots.

Based on our experience, a modest hardware like 3.2 dual core CPU, 3.2Gb memory under Windows, 1Gb network adapter can provide acceptable performance for the following setup:

• 60 projects and 300 build configurations

...

• (with one forth being active and running regularly);
• more then 300 builds a day;
• about 2Mb log per build;
• 50 build agents;
• 50 web users and 30 IDE users;
• 100 VCS roots (mainly Perforce and Subversion using server checkout), average checking for changes interval is 120 seconds;
• more then 150 changes per day;
• the database (MySQL) is running on the same machine, main TeamCity process has -Xmx1100m -XX:MaxPermSize=120m JVM settings.

However, to ensure peak load can be handled well, more powerful hardware is recommended.

HDD free space requirements are mainly determined by the number of builds stored on the server and the artifacts size/build log size in each.

...

The general recommendation for deploying large-scale TeamCity installation is to start with a reasonable hardware and add more projects to the server gradually, monitoring the performance characteristics and deciding on necessary hardware or software improvements. Anyway, best administration practices are recommended like keeping adequate disk defragmentation level, etc.

If you consider cloud deployment for TeamCity agents (e.g. on Amazon EC2), please also review Setting Up TeamCity for Amazon EC2

Setup TeamCity in Replication/Clustering Environment

TeamCity does not provide specific support for any of replication/high availability or clustering solutions; however you can replicate the data that TeamCity server uses and prepare to start a new server using the same data if existing server malfunctions.

When setting up TeamCity in a replication environment please note that TeamCity uses both database and file storage to save data. You can browse through TeamCity Data Backup and TeamCity Data Directory pages in to get more information on TeamCity data storing.

...

Only single TeamCity server instance should use database and data directory at any time.

Please also ensure that the distribution of the backup server is of exactly the same version as the main server.

See also information on switching from one server to another.

Move TeamCity projects from one server to another.

Generally, this moving projects to a server that already have projects/build configurations configured is not supported. For addressing simple cases manually, please see a comment.

...

If you need a level of automation and web administration UI does not suite your needs, there are two possibilities:

• change configuration files directly on disk (see more at TeamCity Data Directory)
• write a TeamCity Java plugin that will perform the tasks using open API.

Create a copy of TeamCity server with all data

One of the ways to create a copy of the server is to create a backup, then install a new TeamCity server of the same version that you already run, ensure you have appropriate environment configured, ensure that the server uses own TeamCity Data Directory and database and then restore the backup.
This way, the backup will not contain:

• the build artifacts, so if you need them, you will need to copy .BuildServer/system/artifacts from the original server to the copied server.
• .BuildServer/plugins - copy the directory if you have it
• .BuildServer/lib - copy the directory if you have it

If you do not want to use bundled backup functionality or need manual control over the process, here is a description of the general steps you will usually need to make to create copy of the server:

1. create a backup so that you can restore it if anything goes wrong
2. ensure the server is not running
3. either perform clean installation or copy TeamCity binaries (TeamCity home directory) into the new place temp and work subdirectories can be omitted during copying). Use exactly the same TeamCity version. If you plan to upgrade after copying, perform the upgrade only after you have existing version up and running.
4. transfer relevant environment if it was specially modified for existing TeamCity installation. This might include:
   • if you run TeamCity with OS startup (e.g. Windows service), make sure all the same configuration is performed on the new machine
   • use the same TeamCity process launching options
   • use appropriate OS user account for running TeamCity server process with appropriately configured settings, global and file system permissions
   • transfer OS security settings if required
   • ensure any files/settings that were configured in TeamCity web UI are accessible; put necessary libraries/files inside TeamCity installation if they were put there earlier)
5. copy TeamCity Data Directory. If you do not need the full copy, refer to the items below for optional items.
   • .BuildServer/config to preserve projects and build configurations settings
   • .BuildServer/lib and .BuildServer/plugins if you have them
   • files from the root of .BuildServer/system (most importantly, version.dat). The file license.keys contains license key, and you can copy it only if you make the copy for backup/evaluation purposes.
   • .BuildServer/system/messages (optional) if you want build logs (including tests failure details) preserved on the new server
   • .BuildServer/system/artifacts (optional) if you want build artifacts preserved on the new server
   • .BuildServer/system/changes (optional) if you want personal changes preserved on the new server
   • .BuildServer/system/caches and .BuildServer/system/caches (optional) are not necessary to copy to the new server, they will be recreated on startup, but can take some time to be rebuilt (expect some slow down).
6. create copy of the database that your TeamCity installation is using in new schema or new database server
7. configure new TeamCity installation to use proper TeamCity Data Directory and database (.BuildServer/config/database.properties points to a copy of the database)

Note: if you want to do a quick check and do not want to preserve builds history on the new server you can skip step 6 (cloning database) and all items of the step 5 marked as optional.

At this point you should be ready to run the copy TeamCity server.

Please note that TeamCity Data Directory and database should be used by a single TeamCity instance at any given moment. If you configured new TeamCity instance to use the same data, please ensure you shutdown and disable old TeamCity instance before staring a new one.

1. run new TeamCity server
2. upon new server startup do not forget to update Server URL on Server configuration administration page. You will also probably need to modify Email and Jabber notification sending settings to prevent new server from sending out notifications
3. if you need the services on the copied server check that email, jabber and VCS servers are accessible from the new installation.
4. install new agents (or select some form the existing ones) and configure them to connect to the new server (using new server URL)

Test-drive newer TeamCity version before upgrade

It's advised to try new TeamCity version before upgrading your production server. Usual procedure is to create a copy of your production TeamCity installation, then upgrade it, try the things out and when everything is checked, drop the test server and upgrade the main one.

You can get an evaluation license for the new server at the official download page.

How do I choose OS/platform for TeamCity server?

Once the server/OS fulfills the requirements, TeamCity can run on any system. Please also review the requirements for the integrations you plan to use (e.g. integration with Microsoft TFS and VSS will work only under MS Windows)

If you have no preference, Linux platforms may be more preferable due to more effective file system operations and the level of required general OS maintenance.

Final Operating System choice should probably depend more on the available resources and established practices in your organization.

If you choose to install 64 bit OS, TeamCity can run under 64 bit JDK (both server and agent).
However, unless you need to provide more then 1Gb memory for TeamCity, the recommended approach is to use 32 bit JVM even under 64 bit OS. Our experience suggests that using 64 bit JVM does not increase performance a great deal. At the same time it does increase memory requirements to almost the scale of 2. See a note on memory configuration.

How do I set up deployment for my application in TeamCity

1. Write a build script that will perform the deployment task for the binary files available on the disk. (e.g. use Ant for this)
2. Create a build configuration in TeamCity that will execute the build script.
3. In this build configuration configure artifact dependency on a build that produces binaries that need to be deployed
4. Configure one of the available triggers if you need the deployment to be triggered automatically (e.g. to deploy last successful of last pinned build), or use "Promote" action in the build that produces the binaries that need to be deployed.
5. If you need to parametrize the deployment (e.g. specify different target machines in different runs), pass parameters to the build script using custom build run dialog

Integrating with Reporting/Metric Tools

If you have a tool that generates some report or provides code metrics, you may want to display the data in TeamCity.

The integration tasks involved are collecting the data in the scope of a build and then reporting the data to TeamCity so that they can be presented in the build results or in other ways.

Data collection
The easiest way for a start is to modify your build scripts to make use of the selected tool and collect all the required data.
For an advanced integration a custom TeamCity plugin can be developed to ease tool configuration and running. See XML Test Reporting and FXCop plugin (see a link on Open-source Bundled Plugins) as an example.

Presenting data in TeamCity
For a report, the most simple approach is to generate HTML report in the build script, pack it into archive and publish as a build artifact. Then configure a report tab to display the HTML report as a tab on build's results.

A metrics value can be published as TeamCity statistics via service message and then displayed in a custom chart.

If the tool reports code-attributing information like Inspections or Duplicates, TeamCity-bundled report can be used to display the results. A custom plugin will be necessary to process the tool-specific report into TeamCity-specific data model. Example of this can be found in XML Test Reporting plugin and FXCop plugin (see a link on Open-source Bundled Plugins).

For advanced integration, a custom plugin will be necessary to store and present the data as required. See Developing TeamCity Plugins for more information on plugin development.
