Cisco IP SLA issues

Help
1

Hi,
some of my cisco devices with IP SLA are alerting a down state, There is a SLA ID’s which were never
created by myself and exist in the cisco config, so the slas.opstatus is triggering an alert.
In the Log-File i see the following:

Error in slas module. SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry ‘1207-11’ for key ‘slas_device_
id_sla_nr_unique’ (SQL: insert into slas (deleted, sla_nr, owner, tag, rtt_type, rtt, status, opstatus, device_id) values (0, 11.3, , , , ?, 0, 2, 1207))

It seems the PR: Fix possible null error in SLA modules #13046
is causing this issue.
When I reverted the changes on my Test-LNMS machine , it seems to work again and no “death,” sla id appear again and everything works fine.
On discord there was another guy who reported this issue as well.
I know this fix should solve this “null error” thing, but it seems there came another one into it.

ciao

I had this exact same issue on IOS-XE/IOS-XR. Basically every time the device is rediscovered the Null SLAs return. Even after deleting the SLAs in the SQL database and removing the RRD files.

Hi,
a fix has been released by murrant today. Works great now. Thank you @murrant.

Issue was extra data from the device… Double fixed it. Updated the MIB and made the code ignore bad entries.
