Monitor

Monitor

Monitoring the Chef server involves two types of checks: application and system. In addition monitoring the HTTP requests that workstations and nodes are making to the Chef server and per-disk data storage volumes is recommended.

Monitoring Priorities

The following sections describe the priorities for monitoring of the Chef server. In particular, running out of disk space is the primary cause of failure.

Disks

Over time, and with enough data, disks will fill up or exceed the per-disk quotas that may have been set for them and they will not be able to write data. A disk that is not able to write data will not be able to support certain components of the Chef server, such as PostgreSQL, RabbitMQ, service log files, and deleted file handles. Monitoring disk usage is the best way to ensure that disks don’t fill up or exceed their quota.
