v89 Antoine Beaupré
prometheus: document how to trace a metric
v88 Antoine Beaupré
prom: document why we don't do puppetdb (tpo/tpa/team#40675)
v87 Antoine Beaupré
prom: move up mobile notifs This fits better with the other stuff above, than below the migrations
v86 Gabriel Filion
prometheus: Fill in the TODO left in the page. refs: tpo/tpa/team#41655
v85 Gabriel Filion
prometheus: Fill in some missing parts of documentation refs: tpo/tpa/team#41655
v84 Antoine Beaupré
move reboots procedures to its own page
v83 Antoine Beaupré
remove references to nagios in our docs (tpo/tpa/team#41816) We stop short of rewriting all playbooks for Prometheus, and instead add references to the task of adding playbooks for everything (tpo/tpa/prometheus-alerts#16) where we found references to nagios.
v82 Antoine Beaupré
prometheus: expand the metrics and storage section I was trying to show how much disk space Prometheus was using and couldn't find good answers.
v81 Antoine Beaupré
prom: cross-ref logging
v80 Antoine Beaupré
document how "value" works in promtool unit tests
v79 Gabriel Filion
prom: move ref to relabeler site higher in the paragraph This tool is super useful to get acquainted with relabeling rules, so it should be mentioned before we dive into more examples. This way ppl can start playing with relabeling rules faster and even test our examples.
v78 Gabriel Filion
prometheus: fix example for node exporter The parentheses were necessary in the actual solution since the action uses a regex in the `replacement` option which defaults to `$1` -- so it expects to output the first matched group!
v77 Antoine Beaupré
prom: contrast relabeling with recording rules minimally
v76 Antoine Beaupré
document what we learned about metric relabeling (tpo/tpa/team#41642)
v75 Gabriel Filion
Merge some information I had added to prometheus into incident-response There's a section about finding information in Nagios which I don't know how to translate to prometheus, so I left it there, but we'll want to remove and/or review that.
v74 Gabriel Filion
New playbook for when a host is unreachable We're splitting the alert for hosts being unreachable / unresponsive so that we can have a better severity level and instructions for how to handle this case. Unreachable hosts can be caused by a number of things so it's important to systematically investigate what's happening.
v73 Antoine Beaupré
fix borken link
v72 Antoine Beaupré
document possible keepalive snafu (tpo/tpa/team#41902)
v71 Antoine Beaupré
expand on the labels examples (tpo/tpa/team#41868)
v70 Gabriel Filion
Clarify meaning of labels regarding indirect metrics like blackbox (tpo/tpa/team#41868) The labels that were previously there did not have enough granularity for cases where we use the blackbox exporter. The meaning of some of the labels, like `instance` and `alias` was blurred over time and the information it contains seems to vary in semantics. For some alerts, we need to know about the blackbox target as well as the host that's concerned. This change to the documentation clarifies that instance only has one stable semantic and that alias label is always used for containing the hostname that we as humans would think of when referring to metrics. To complete the picture, we're adding the `target` label that will contain the blackbox target, which will untangle the meaning of the `alias` label.
