bpf-map-pressure-exporter
bpf-map-pressure-exporter exposes BPF map pressure.
Config
Default config file is /etc/bpf-map-pressure-exporter/config.yaml.
The target BPF maps should be specified under mapNames.
mapNames:
- cilium_ct
- ...
fetchInterval: 30s
mapNames are interpreted as substrings of the map names and the pressure metrics for all maps including the substring are exposed.
If multiple mapNames are specified and some of them match the same map, only 1 metric is exposed.
Note that BPF map names are truncated to 15 characters.
fetchInterval defines the time interval to fetch BPF map pressure.
bpf-map-pressure-exporter fetches the map pressure of target maps every fetchInterval and returns the latest value when scraped.
Default value is 30s.
