monitor

Two monitoring stacks to play with here.

Don't use either of these for production as they are wide open to abuse.

Prometheus/Grafana

Prometheus, Grafana, Prometheus Pushgateway and the Prometheus Node Exporter

docker-compose up

I have Cockpit running on port 9090 so I mapped prometheus to 9900

Push Gateway

Metrics can be pushed to the prometheus via the PushGateway using the test script in the scripts directory.

Prometheus container fails to start?

se-linux might be set to enforcing which can cause problems with docker volumes

Either set it to permissive or run:

chcon -Rt svirt_sandbox_file_t ./prometheus.yml

or use :z on the volume:

- ./config/prometheus.yml:/etc/prometheus/prometheus.yml:z

TICK Stack

Influxdb, Chronograf, Telegraf, Kapacitor,

docker-compose up -f docker-compose-influx.yml up

Elasticsearch / Kibana

docker-compose up -f docker-compose-elasticsearch.yml up

Latest docker image 6.5.4 fails to start on Fedora with

[1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

Workaround is

sysctl -w vm.max_map_count=262144

or make this change permanent by editing /etc/sysctl.conf

Image started OK on Mojave.
