SigarProvider

trait SigarProvider

Provide sigar instance as SigarProxy.

User can provision sigar classes and native library in one of the following ways:

  1. Use Kamon sigar-loader as a project dependency for the user project. Metrics extension will extract and load sigar library on demand with help of Kamon sigar provisioner.

  2. Use Kamon sigar-loader as java agent: java -javaagent:/path/to/sigar-loader.jar Kamon sigar loader agent will extract and load sigar library during JVM start.

  3. Place sigar.jar on the classpath and sigar native library for the o/s on the java.library.path User is required to manage both project dependency and library deployment manually.
