Monitoring
Roadblocks
-
-
Initial a high number of alerts caused an overload and important things were missed. This was addressed by:
- tuning thresholds
- bundling errors
- directing alerts to the team which can address them.
- logging is reviewed and adjusted in each part of the application to follow a common concept and importance.
Systems outside of IFES and their monitoring were not aligned initially.
- a common alert handling process was established.
- a common mask of error reporting.
- thresholds are defined per system in line with severity definitions.
It's hard to integrate and correlate logs across systems.
- introduce a correlation id (GUID)
-
The infrastructure of Elastic search has been hardened:
- failover cluster
- backup strategy has been established
- costs have been accepted by the management
