Lost historical data

Help
1

Hi Guys

Wondering if anyone can help me

Noticed today that all the historical data has been lost from all devices and all graphs across the entrie install. and is only showing data as of 09:00 this morning.
Checked the syslog for the server nothing jumping out

I then run the validate PHP and it was showing an issue as below

librenms@htl-libre-nms:~$ ./validate.php

Component Version
LibreNMS 21.8.0-52-gb2d34cac4
DB Schema 2021_08_26_093522_config_value_to_medium_text (217)
PHP 7.4.3
Python 3.8.10
MySQL 10.3.31-MariaDB-0ubuntu0.20.04.1
RRDTool 1.7.2
SNMP NET-SNMP 5.8

====================================

[OK] Composer Version: 2.1.6
[OK] Dependencies up-to-date.
[OK] Database connection successful
[OK] Database schema correct
[WARN] Your local git contains modified files, this could prevent automatic updates.
[FIX]:
You can fix this with ./scripts/github-remove
Modified Files:
rrd/.gitignore

I then run ./scripts/github-remove -d to remove the error and run it again now showing as no issues

librenms@htl-libre-nms:~$ ./validate.php

Component Version
LibreNMS 21.8.0-52-gb2d34cac4

This is the only thing I can see that was out of place which is now resolved

Any help would be great

Kind Regards

Just some further info
We still have all the events log and syslog history
and we also still have the latancy perfrmance data

Just seems to be all the ports across all devices and memory, CPU, Sessions etc etc

Did you change something with rrdcached or your rrd_dir location?

Hi Murrant

No changes have been made the last change was a couple of devices being added a few days before.

From 09:00 today onwards the graphs are showing just no histrical

There was a huge spike at 08:50 in read/writes to the disk but the disk size has remand the same so it has not dumped the data

Kind Regards

Decided to role back the install to another save point and we see if it does it again
