But it doesn’t have to be, and in the original problem that was exactly the situation. Most of the plugins are for time-series databases such as Prometheus and InfluxDB, specialising in storing metrics. These new objects get written to S3. The query result cache may therefore have positive or negative effects on query execution times, depending on the workload: it will not make much sense turning on the cache in write-only or write-mostly scenarios, but the cache may be very beneficial in case workloads are read-only or read-mostly, and query are complex. Log Queries. These can be written in JavaScript (V8js or Node. The following shows an example Grafana dashboard which queries Prometheus for data:.

Some observations: The request to read the M-Bus data seems to fail on a fairly regular basis (10-20% of the time) so the script needs to check for that and re-run the query until a response is received from each meter. Useful to compare different series where the values in each series may be higher or lower on average but you’re only interested in the relative difference.
