Add cleanup of the lockfile when the db is cleanly closed The metric describes the status of the lockfile on startup 0: Already existed 1: Did not exist -1: Disabled Therefore, if the min value over time of this metric is 0, that means that executions have exited uncleanly We can then use that metric to have a much lower threshold on the crashlooping alert: If the metric exists and it has been zero, two restarts is enough to trigger the alarm If it does not exist (old prom version for example), the current five restarts threshold remains Signed-off-by: Julien Duchesne <julien.duchesne@grafana.com> * Change metric name + set unset value to -1 Signed-off-by: Julien Duchesne <julien.duchesne@grafana.com> * Only check the last value of the clean start alert Signed-off-by: Julien Duchesne <julien.duchesne@grafana.com> * Fix test + nit Signed-off-by: Julien Duchesne <julien.duchesne@grafana.com> |

Prometheus Mixin
This is work in progress. We aim for it to become a good role model for alerts and dashboards eventually, but it is not quite there yet.
The Prometheus Mixin is a set of configurable, reusable, and extensible alerts and dashboards for Prometheus.
To use them, you need to have jsonnet
(v0.13+) and jb
installed. If you
have a working Go development environment, it's easiest to run the following:
$ go get github.com/google/go-jsonnet/cmd/jsonnet
$ go get github.com/google/go-jsonnet/cmd/jsonnetfmt
$ go get github.com/jsonnet-bundler/jsonnet-bundler/cmd/jb
Note: The make targets lint
and fmt
need the jsonnetfmt
binary, which is
available from v.0.16.0 in the Go implementation of jsonnet
. If your jsonnet version is older than 0.16.0 you have to either upgrade or install the C++ version of
jsonnetfmt if you want to use make lint
or make fmt
.
Next, install the dependencies by running the following command in this directory:
$ jb install
You can then build a prometheus_alerts.yaml
with the alerts and a directory
dashboards_out
with the Grafana dashboard JSON files:
$ make prometheus_alerts.yaml
$ make dashboards_out
