Host agent versioning
Different versions of the Instana agent appear in the Instana UI and in the IBM Documentation. To collect the various versions, see the following information:
Agent Boot (strap) version
The Agent Boot (strap) version is released as part of the assemblies, packages, and containerized agents. It tracks the static dependencies that don't change often.
Reinstall the agent to upgrade the version on both the Static and Dynamic agents.
Agent version
Agent version works with the boot (strap) and the sensors. 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
Small 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.
