* Implement ACL support for redis (and sentinel)
Currently, sentinel only works with anonymous connections.
Some parameters are passed when using sentinel, however these are
dropped on the floor.
This encapsulates them as py-redis expects, and passes them correctly.
* Pass username
* Differentiate duplicate error messages
* Actually pass var
* Docs and requirement bump
* Lint
* Consistency
* More lint
* Lint harder
* Doc Updates
There are two systemd service files suggested for use, only one should be used. My changes clarify the usage and adjust the librenms-watchdog.service to install as librenms.service as that appears to be the intention from #12188
* Use GitLab instead of Gitlab
Only change text part, the Alert.Transport.Gitlab class left as is.
* Fix href in document
* Move section in document
The agent list in this document is sorted by alphabetical order,
"SDFS info" is the only exception.
* Remove trailing spaces in document
* Align code in document
* Fix Markdown in document
- Escape underline
- Add syntax highlight
- Add two space in the end of line to make it a newline
- Add newline before list or code section
* Update LibreNMS/Alert/Transport/Gitlab.php

* Update Documentation
Most work in Graylog and SNMP
Fixed many code tags, spelling and wording.
Added SNMP PowerShell example.
* Update SNMP-Configuration-Examples.md
Fix TOC brackets
* Implement locks in the file cache
* Replace custom locks
* implement restore lock
Used when re-hydrating
* remove legacy use statements
* Add class descriptions
* Fix style
* Default to database cache driver
* missed cache_locks table
prevent chicken-egg issue
* style fixes
* Remove custom file lock implementation
* missed items from file cache
* Update schema definition
hmm, other schema noise must be from manual modification as this is generated from a freshly migrated db.
* require predis, it is pure python, so no harm in adding
* and set predis as the default client
* Handle more signals
* Flush buffers before exiting process
This ensures log messages aren't lost
* Restart process before jobs have finished
If there is a very log running job it can cause service restart to
take over 5 minutes.
We tweak the order of things to make sure that running processes
continue, but nothing more is scheduled.
The worst case impact is that a pollling/discovery job gets
scheduled twice, but this should not be a big issue - this should
only occur at most once per day.
* Remove python 3.8 feature
* Ensure that processes from the previous invocation are reaped
* Correct typo's
* Attach subprocess descriptors to /dev/null
Occasionally, PHP would throw a fit and crash when its stdout went
away. To avoid this, we attach stdout to devnull.
This means we lost output of daily.sh - but this is already recorded
in $LOGDIR/daily.log
* Don't immediately schedule long running jobs
To avoid the situation where the maintenance reload happens or a sighup,
then a second long running job is immediately started, we wait
(`last_[poll/discovery]_timetaken` * 1.25) seconds before scheduling
any jobs.
* Add `psutil` to requirements
* Add support for "systemctl reload" to the unit files
* Add a fallback for systems that don't have psutil
* Reduce CPU load when psutil is not installed
* Don't avoid double polling by extending the timeout
This shouldn't happen due to locks
* Remove fallback option
* Remove extra variable
* Fix issue introduced during rebase
* Fix issue introduced when fixing issue introduced during rebase
* Make psutil optional
