Monitoring SolCache

This section describes how you can use to configure event parameters on a per Cache Cluster basis and how to monitor events and logs generated by SolCache Instances. It also describes the show commands you can use to monitor the SolCache configuration and operational status, and provides some guidance for using Solace Element Management Protocol (SEMP) to monitor and manage a SolCache implementation.

SolCache Events

Each SolCache Instance uses an event queue with a maximum depth of ten events, and it only removes an event from this queue once it gets an acknowledgment (that is, an ACK) back from the Cache Manager. If its queue is full, the SolCache Instance raises syslog events locally until a connection to the message bus is established. It can:

  • locally raise the VPN_SOLCACHE_LOSS_OF_NOTIFICATION event
  • locally raise the event that could not be sent back to the cache manager

For a complete list of SolCache events, refer to SolOS Event Reference, which lists and describes SolOS syslog messages related to system-wide, Message VPN, and local client SolOS events.
