Grok-Exporter

The Grok-Exporter can be used to read metrics from log files or to add up the number of entries in logs. It is similar to Promtail in that it also scrapes log files.

However, the Grok exporter only evaluates patterns and either returns numerical values (gauges) determined from the corresponding lines or reports that or how many lines (counters) of a certain pattern have occurred.

This can be used to determine whether certain errors/abnormalities have occurred.
On the other hand, the times of the LogDB accesses from INUBIT or the JMS queue size of the AS4 gateway, which are written numerically in the respective logs, can also be mapped in VIMON.
