Host agent versioning

Agent boot (strap) version

The Agent boot (strap) version is released as part of the assemblies, packages, and containerized agents. It tracks the consistent part of the agent runtime that does not change often. The Agent boot (strap) version is crucial for the agent support lifecycle. For more information, see Support policy for Instana agent.

You need to reinstall the agent to upgrade the agent boot strap version on both the Static and Dynamic agents.

Agent version

The Agent version works with all boot (strap) versions and describes Instana tracers and the sensors for the agent. The Agent version serves as a BOM for the running agent. The Instana UI shows the current agent version in the format YYYY.MM.DD-HHMM (Year.Month.Day-HourMinute).

The overview of Agents also shows this version.

You can find all the other versions (SHA checksums) in the agent-updates Git repository. In addition to the commit sha, the version is also released as a tag. The tags can be found in Agent Updates - tags.

To see the version of the agent, you can locally access the API of the agent: curl localhost:42699/.

With the static agent, both the boot and the agent are updated at the same time (boot is updated, if needed).

Agent sensor version

Minor components are added to the agent to monitor specific technology stack and are enabled if the technology is present in the same location where the agent is installed. For example, the Go sensor.

Each sensor itself decides what and how to monitor a technology.

Version pinning

To use a specific version with a dynamic agent, follow the steps that are mentioned in Version pinning.
