# Install validation
With a lot of configuration possibilities, manually editing config.php
means it's not uncommon that mistakes get made. It's also impossible
to validate user input in config.php when you're just using a text
editor :)
So, to try and help with some of the general issues people come across
we've put together a simple validation tool which at present will:
- Validate config.php from a php perspective including whitespace
where it shouldn't be.
- Connection to your MySQL server to verify credentials.
- Checks if you are running the older alerting system.
- Checks your rrd directory setup if not running rrdcached.
- Checks disk space for where /opt/librenms is installed.
- Checks location to fping
- Tests MySQL strict mode being enabled
- Tests for files not owned by librenms user (if configured)
Optionally you can also pass -m and a module name for that to be
tested. Current modules are:
- mail - This will validate your mail transport configuration.
- dist-poller - This will test your distributed poller configuration.
- rrdcheck - This will test your rrd files to see if they are
unreadable or corrupted (source of broken graphs).
You can run validate.php as `root` by executing `./validate.php`
within your install directory.
The output will provide you either a clean bill of health or a list of
things you need to fix:
**OK** - This is a good thing, you can skip over these :)
**WARN** - You probably want to check this out.
**FAIL** - This is going to need your attention!
# Validate from the WebUI
You can validate your LibreNMS install from the WebUI, using the nav
bar and clicking on the little Gear Icon -> Validate Config.
Then You should see the results of validate.
Below is just example of the results.
