# Important log files

## On the Trilio Nodes

The Trilio Cluster contains multiple log files.

The main log is workloadmgr-workloads.log, which contains all logs about ongoing and past Trilio backup and restore tasks. It can be found at:

`/var/log/workloadmgr/workloadmgr-workloads.log`

The next important log is the workloadmgr-api.log, which contains all logs about API calls received by the Trilio Cluster. It can be found at:

`/var/log/workloadmgr/workloadmgr-api.log`

The log for the remaining service is the workloadmgr-scheduler.log, which contains all logs about the internal job scheduling in the Trilio Cluster.

`/var/log/workloadmgr/workloadmgr-scheulder.log`

## On the Controller node (nova-api extension)

The logs for the nova-api extension can be found here:

`/var/log/nova/nova-api.log`

## On the Compute nodes (datamover)
