I’m a long time observium user and new librenms docker user…

I have a bare metal Fedora 35 (not that it matter much but in case it might)

I didn’t migrate anything from observium, I manually added hosts…

First I did the docker clone…
git clone --depth=1 docker-librenms

Then the usual
docker-compose -f /root/docker-librenms/examples/compose/docker-compose.yml [pull, create, up]

After a few days I noticed that I didn’t have rrdcached… figured out I needed a new docker-compose for that…

docker-compose -f /root/docker-librenms/examples/rrdcached-server/docker-compose.yml [pull, create, up, etc…]
(which it looked like that gave me rrdcached… please let me know if it didn’t… )

figured out that I lost all my nodes and data… so I manually added big important things, and figured out that I cannot figure out how the msmtpd.env works… (rrdcached was more important…) I got default alerts, and notifications, going… etc… now I’m getting emails…

But these emails…

For example:

Alert for device - State Sensor Critical
Severity: critical
Timestamp: 2021-11-22 15:12:16
Unique-ID: 588
Rule: State Sensor Critical Faults:
#1: sysObjectID = .; location_id = 12; sensor_id = 808; sensor_oid = .; sensor_descr = Health; state_descr = critical;
Alert sent to: is an eql4210 there is a sensor that librenms finds called ‘Health’ (observium doesn’t have this) and is reporting a 3 (the rrdgraph is a flat 3 for the past two weeks, etc…)

Not sure what that is…

snmpget -v 2c -c xyz1232^2=4 .
SNMPv2-SMI::enterprises.12740. = INTEGER: 3

the snmp poll does return a 3…

and /opt/librenms/mibs/dell … there is no answer for what it is… hence the numeric oid…

I can’t even find on dell’s site the MIBs listed in librenms…

There is a secondary email that comes every five minutes when the other email comes…

Alert for device - Sensor over limit - Check Device Health Settings
Severity: critical
Timestamp: 2021-11-22 15:12:16
Unique-ID: 583
Rule: Sensor over limit - Check Device Health Settings Faults:
#1: sysObjectID = .; location_id = 12; sensor_id = 808; sensor_oid = .; sensor_descr = Health;
#2: sysObjectID = .; location_id = 12; sensor_id = 834; sensor_oid = .; sensor_descr = Disk 24 - S3L1HDDY;
Alert sent to:

(great that gives me a disk to look at… )

Disk 24 is a spare, and it’s state has a return value of 2.

[] :: Sensor :: Disk 24 - S3L1HDDY :: State

Oddly enough… this url

shows ‘No Storage’ (in blue)

I would like to confirm if this is some sort of actual error, observium doesn’t register a problem, and if it is a problem, I’d like to get more information about it so that I could put information into an issue report… (and if it isn’t a problem) how do I stop the messages from coming, or at least ack them in the mean time…

Thanks in advance for taking the time to read all of this…

Probably the spare state is set to the wrong generic status…

unknown (0),
normal (1),
warning (2),
critical (3)

So, 3 = critical.

eqlDiskStatus OBJECT-TYPE
on-line (1),
spare (2),
failed (3),
off-line (4),
alt-sig (5),

2 is spare, which is marked as 0 in LibreNMS (ok).

You sure the device didn’t have an issue?

  1. The device reported incorrect data. (not likely)
  2. The device had a transient error. (or persistent if still alarming)
  3. Your alert rules are not quite right and giving false alarms.
