Most release job only start a single process.Installation and Configuration: Follow step-by-step instructions to install and configure Monit on your server. This is how you can tell which processes belong to which release job. var/vcap/jobs/redis-server/monit) with final monit configuration for that release job. Each release job directory contains a monit file (e.g. Switch to become a root user (via sudo su or sudo -i) since MonitĮxecutable is only available to root users.Įach enabled release job has its own directory in /var/vcap/jobs/ directory. Before you can run the monit command you have to On any BOSH-managed VM, you can access Monit status for release jobs' To determine what the problem is with a specific VM, you can ssh into the VM and look at the logs and/or Monit directly. Unresponsive: the Director did not receive any response from the Agent Starting state indicates that one or more of the release jobs' processes are being started and may not yet be running. Starting: the Director received a response from the Agent and the Agent reported its aggregate status as starting. Failing state indicatates one or more of the release jobs' processes is not successfully running (could be failing to start, or exiting after some time, or still in the process of becoming healthy, etc.). Running state indicates that all release jobs' processes are successfully running at that moment.įailing: the Director received a response from the Agent and the Agent reported its aggregate status as not successful. Running: the Director received a response from the Agent and the Agent reported its aggregate status as successful.
