85c1ccb8b8 app/vminsert/netstorage: add missing return in storageNode.checkHealth on connection failure 2020-06-18 20:51:51 +03:00
Aliaksandr Valialkin
464682f380 app/vminsert/netstorage: periodically check for each -storageNode health, so it could be marked as healthy when it is ready to accept data 
This fixes uneven data routing in cluster version when `-replicationFactor` is set to 1 (default value),
i.e. when the replication is disabled.

1a01fe2cf2 vmalert-537: allow name duplication for rules within one group. (#559) 
Uniqueness of rule is now defined by combination of its name, expression and
labels. The hash of the combination is now used as rule ID and identifies rule within the group.

Set of rules from coreos/kube-prometheus was added for testing purposes to
verify compatibility. The check also showed that `vmalert` doesn't support
`query` template function that was mentioned as limitation in README.

936f35920a app/vmselect/prometheus: allow returning partial response from /api/v1/export if -search.denyPartialResponse=false 
This makes `/api/v1/export` behaviour consistent with other `/api/v1/*` handlers.

e4cef1b678 app/vmstorage: prevent from serving conns from vminsert and vmselect after the server is closed 
Previously it was possible that the connection is served after the server is closed if the following
steps are performed:

1) Server accepts new connection.
2) Server.MustClose() is called and successfully finished.
3) Server starts processing the connection accepted at step 1. There could be various crashes
   like in https://github.com/VictoriaMetrics/VictoriaMetrics/issues/534 since the storage may be already closed.

Now the server closes the connection at step 3 without processing it.

44c51c627f vmalert: Add recording rules support. (#519) 
* vmalert: Add recording rules support.

Recording rules support required additional service refactoring since
it wasn't planned to support them from the very beginning. The list
of changes is following:
* new entity RecordingRule was added for writing results of MetricsQL
expressions into remote storage;
* interface Rule now unites both recording and alerting rules;
* configuration parser was moved to separate package and now performs
more strict validation;
* new endpoint for listing all groups and rules in json format was added;
* evaluation interval may be set to every particular group;

* vmalert: uncomment tests

* vmalert: rm outdated TODO

* vmalert: fix typos in README
