ClickHouse monitoring is part of Instana’s automated Application Performance Monitoring solution.
When the Instana agent is deployed into an infrastructure containing ClickHouse, it automatically detects the technology and configures itself to monitor ClickHouse along with its configuration data and performance metrics. No human setup or configuration is required.
ClickHouse Performance and Configuration Monitoring
After Instana automatically deploys its ClickHouse monitoring, it will immediately map out ClickHouse’s infrastructure. The Instana agent sends all data back to our Dynamic Graph model, which stores and contextualizes all collected monitoring data. Typical configuration data collected are:
- http_port
- tcp_port
- https_port
- tcp_ssl_port
- log
- error_log
- etc.
Some example metrics collected are:
- Merge
- ReplicatedFetch
- ReplicatedSend
- ReplicatedChecks
- BackgroundPoolTask
- DiskSpaceReservedForMerge
- DistributedSend
- QueryPreempted
- etc.
