Managing the Job Cache¶

The Salt Master maintains a job cache of all job executions which can be queried via the jobs runner. This job cache is called the Default Job Cache.

Default Job Cache¶

A number of options are available when configuring the job cache. The default caching system uses local storage on the Salt Master and can be found in the job cache directory (on Linux systems this is typically /var/cache/salt/master/jobs). The default caching system is suitable for most deployments as it does not typically require any further configuration or management.

The default job cache is a temporary cache and jobs will be stored for 24 hours. If the default cache needs to store jobs for a different period the time can be easily adjusted by changing the keep_jobs parameter in the Salt Master configuration file. The value passed in is measured via hours:

keep_jobs: 24

Additional Job Cache Options¶

Many deployments may wish to use an external database to maintain a long term register of executed jobs. Salt comes with two main mechanisms to do this, the master job cache and the external job cache.
