Call-home / Alerting
QuantaStor has a number of mechanisms for call-home alerting when Storage Systems within the grid report hardware and software issues. They include standard mechanisms like email and SNMP but also include various cloud based call-home mechanisms which are "web-hook" based.
- SNMP
- WebHooks
- User supplied custom Alert Handler (see /opt/osnexus/quantastor/bin/qs_alerthandler_sample.py and /opt/osnexus/quantastor/conf/qs_alerthandlers.conf for more information)
The Alert Manager also allows one to specify thresholds for low capacity on Pools, Buckets, and Network Share Quotas. Administrators should take action to expand the available capacity of the cluster to ensure continuous normal operation of systems whenever a pool exceeds 80% full and ideally at 70% full. Performance can degrade when the pool fills beyond 90% full depending on the level of fragmentation.

The Alert Manager documentation has moved to Alert Manager / Call-home Alerting.
Generating Alerts
QuantaStor systems report alerts at various severity levels including INFO, ERROR and WARNING. For example, when a disk needs to be replaced it will produce a WARNING and some ERROR level events from the controller which in turn generate alerts. Alerts are sent via all configured mechanisms so a system with email and PagerDuty configured will see events send to administrators both via email and PagerDuty mechanisms. To generate a test alert one may use the qs alert-raise QS CLI command or use the Generate Test Alert button in the QuantaStor web management interface.
