So far, the documentation has claimed that loggers have a default severity
(information for FileLogger and warning for SyslogLogger). However, this was
not the case and not setting the severity resulted in a configuration error.
This commit changes the default value to be information for all loggers.
This commit adds a timeout for both establishing new outgoing and incoming
connections. This timeout applies to everything until the connection is in a
state where either JsonRpcConnection or HttpServerConnection takes over.
Disregard passive check results while no active checks are being scheduled due to violated dependencies.
This copes with the fact that programs feeding passive check results into Icinga may have no notion of reachability and so drive a checkable into HARD state although dependencies have caused active check scheduling being suspended. This may prevent superflous problem notifications being emitted during recovery.
As disable_checks defaults to false, it was regarded OK (by @Al2Klimov) to make this behaviour (which resembles the active check case) unconditional and not conditionalize it on an additional attribute.
In the description of disable_checks, note that a value of true both disables scheduling of active checks and drops passive check results.
Note: This drops the deprecated concurrent_checks setting from the checker feature
entirely and refactors the underlaying code handling.
Also affects ReloadTimeout which is new for 2.11.
fixes#7111
- Decrease Object Authority updates to 10s (was 30s)
- Decrease failover timeout to 30s (was 60s)
- Decrease cold startup (after (re)start) with no OA updates to 30s (was 60s)
- Immediately connect on Resume()
- Fix query priority which got broken with #6970
- Add more logging when a failover is in progress
```
[2019-03-29 16:13:53 +0100] information/IdoMysqlConnection: Last update by endpoint 'master1' was 8.33246s ago (< failover timeout of 30s). Retrying.
[2019-03-29 16:14:23 +0100] information/IdoMysqlConnection: Last update by endpoint 'master1' was 38.3288s ago. Taking over 'ido-mysql' in HA zone 'master'.
```
- Add more logging for reconnect and disconnect handling
- Add 'last_failover' attribute to IDO*Connection objects
