More info below. We are seeing the following errors under “/opt/observium/logs/error_log”. Any suggestions?

Show port descriptions also on Ports -> Map view
by Thomas Stather 10 Oct '22

10 Oct '22

Hi We are running Observium Professional r12071 I noticed that if we set up a description for our network ports, these are shown on the views of the switch under Ports -> Basic Ports -> Details Ports -> Neighbours Is there a way to also show it on *Ports -> Map* for the local port (blue bubble) and the remote port (grey bubble)?

Weird results from stacked graph.
by David Milton 07 Oct '22

07 Oct '22

Hello, We have been seeing some results in our stacked graphs that do not appear to make sense. Initially we thought this was because the maximum values for the two values occurred at different points in time. That cannot be the whole issue because even if you take the sum of every pair of numbers the maximum aggregate must at least equal the maximum value of one of the two series. This graph shows the problem: How can we have a maximum value of 97.4M but an aggregate maximum of 55.7M? It seems that maximum aggregate should also at least be 97.4M. What’s happening here? Thanks, Dave.

Alerter frequency
by Alex Rubenstein 04 Oct '22

04 Oct '22

Greetings, I have been setting up Observium for a client for the last few months and I have been loving it. Amazingly flexible and reliable. I am quite pleased. I am running 22.8.12241, Subscription. I know that Observium does not support SNMP Traps and understand why. So, I have set up syslog on the services to push events and they are caught by Observium. This works fine. I have now also created syslog alerts and this works fine too. My issue is the delay from when the syslog comes to the server, and the alert goes out. I found this old mailing list entry: https://lists.observium.org/hyperkitty/list/observium@lists.observium.org/m… Adam's reply was: "We have to wait for a cron job to be run to send the alerts, because we can't do it in the syslog processing script. Iirc you can cron alerter.php to do it more frequently!" This is an acceptable solution to me, but I have a couple question: 1. Is there risk with how often this is run? If I cron'ed this for every minute, is there a risk of some sort of collision with the 5 minute poller? 1. Is it possible, as a feature request, to call alerter.php -h from syslog.php when an entry comes in? While I think Observium is an excellent piece of software, I wish it had just a little more ability to handle real-time alerts coming in. There are many situations that occur where an outage or event could be substantially shorter than the poller interval (like, a short UPS power loss), and I would like to have a little better quasi-real time alerting of these events. Thanks for you consideration.

Temperature sensor question
by Kleber Cristiano Santilli Coelho 30 Sep '22

30 Sep '22

Good Morning! I hope you're all well. I apologize if the question is inappropriate. I'm developing an IOT module and I use the "ENTITY" MIB for the sensors. I saw that Observium handles this MIB automatically, using the entPhySensorType OID to distinguish the sensor types and it works great, except for the temperature sensor, entPhySensorType value 8. I would like to understand if this has any special reason to adapt my code. Thank you, congratulations on the software. -- Kleber Coelho Campus Fernando Costa Universidade de São Paulo (19) 3565-4321

APC's universal I/O (UPS temp/humidity sensors) not showing in
by Steve Costaras 25 Sep '22

25 Sep '22

Have observium polling various APC ups's (AP9631 NMC cards). Observium correctly polls the battery temperatures, but when adding in probes to the universal I/O ports on the AP9631 (just trying with the temp sensor currently) I do not see the data being plotted on observium. Is this supposed to work? I don't have the humidity sensor currently (was trying to test with the temp sensor first before buying the temp/humidity combined sensors for the units). Would really like to get this data tracked for environmental data logging per rack (have a ups per rack). The data does show up in an snmpwalk: # snmpbulkwalk -v2c -c xxx yy.yy.yy.yy .1.3.6.1.4.1.318.1.1.25.1 iso.3.6.1.4.1.318.1.1.25.1.1.0 = INTEGER: 2 iso.3.6.1.4.1.318.1.1.25.1.2.1.1.1.1 = INTEGER: 1 iso.3.6.1.4.1.318.1.1.25.1.2.1.1.2.1 = INTEGER: 2 iso.3.6.1.4.1.318.1.1.25.1.2.1.2.1.1 = INTEGER: 1 iso.3.6.1.4.1.318.1.1.25.1.2.1.2.2.1 = INTEGER: 1 iso.3.6.1.4.1.318.1.1.25.1.2.1.3.1.1 = STRING: "Port 1 Temp 1" iso.3.6.1.4.1.318.1.1.25.1.2.1.3.2.1 = STRING: "Port 2 Temp 2" iso.3.6.1.4.1.318.1.1.25.1.2.1.4.1.1 = STRING: "Port 1" iso.3.6.1.4.1.318.1.1.25.1.2.1.4.2.1 = STRING: "Port 2" iso.3.6.1.4.1.318.1.1.25.1.2.1.5.1.1 = INTEGER: 75 iso.3.6.1.4.1.318.1.1.25.1.2.1.5.2.1 = INTEGER: 90 iso.3.6.1.4.1.318.1.1.25.1.2.1.6.1.1 = INTEGER: 24 (Port 1 temp 1 sensor in C) iso.3.6.1.4.1.318.1.1.25.1.2.1.6.2.1 = INTEGER: 32 (port 2 temp 2 sensor in C) iso.3.6.1.4.1.318.1.1.25.1.2.1.7.1.1 = INTEGER: -1 iso.3.6.1.4.1.318.1.1.25.1.2.1.7.2.1 = INTEGER: -1 iso.3.6.1.4.1.318.1.1.25.1.2.1.8.1.1 = INTEGER: 0 iso.3.6.1.4.1.318.1.1.25.1.2.1.8.2.1 = INTEGER: 0 iso.3.6.1.4.1.318.1.1.25.1.2.1.9.1.1 = INTEGER: 1 iso.3.6.1.4.1.318.1.1.25.1.2.1.9.2.1 = INTEGER: 1 iso.3.6.1.4.1.318.1.1.25.1.2.1.10.1.1 = INTEGER: 2 iso.3.6.1.4.1.318.1.1.25.1.2.1.10.2.1 = INTEGER: 2 iso.3.6.1.4.1.318.1.1.25.1.3.0 = INTEGER: 2 iso.3.6.1.4.1.318.1.1.25.1.4.1.1.1.1 = INTEGER: 1 iso.3.6.1.4.1.318.1.1.25.1.4.1.1.2.1 = INTEGER: 2 iso.3.6.1.4.1.318.1.1.25.1.4.1.2.1.1 = INTEGER: 1 iso.3.6.1.4.1.318.1.1.25.1.4.1.2.2.1 = INTEGER: 1 iso.3.6.1.4.1.318.1.1.25.1.4.1.3.1.1 = STRING: "Port 1 Temp 1" iso.3.6.1.4.1.318.1.1.25.1.4.1.3.2.1 = STRING: "Port 2 Temp 2" iso.3.6.1.4.1.318.1.1.25.1.4.1.4.1.1 = STRING: "Port 1" iso.3.6.1.4.1.318.1.1.25.1.4.1.4.2.1 = STRING: "Port 2" iso.3.6.1.4.1.318.1.1.25.1.4.1.5.1.1 = INTEGER: 0 iso.3.6.1.4.1.318.1.1.25.1.4.1.5.2.1 = INTEGER: 0 iso.3.6.1.4.1.318.1.1.25.1.4.1.6.1.1 = INTEGER: 10 iso.3.6.1.4.1.318.1.1.25.1.4.1.6.2.1 = INTEGER: 10 iso.3.6.1.4.1.318.1.1.25.1.4.1.7.1.1 = INTEGER: 40 iso.3.6.1.4.1.318.1.1.25.1.4.1.7.2.1 = INTEGER: 40 iso.3.6.1.4.1.318.1.1.25.1.4.1.8.1.1 = INTEGER: 60 iso.3.6.1.4.1.318.1.1.25.1.4.1.8.2.1 = INTEGER: 60 iso.3.6.1.4.1.318.1.1.25.1.4.1.9.1.1 = INTEGER: 0 iso.3.6.1.4.1.318.1.1.25.1.4.1.9.2.1 = INTEGER: 0 iso.3.6.1.4.1.318.1.1.25.1.4.1.10.1.1 = INTEGER: 1 iso.3.6.1.4.1.318.1.1.25.1.4.1.10.2.1 = INTEGER: 1 iso.3.6.1.4.1.318.1.1.25.1.4.1.11.1.1 = INTEGER: 1 iso.3.6.1.4.1.318.1.1.25.1.4.1.11.2.1 = INTEGER: 1 iso.3.6.1.4.1.318.1.1.25.1.4.1.12.1.1 = INTEGER: 1 iso.3.6.1.4.1.318.1.1.25.1.4.1.12.2.1 = INTEGER: 1 iso.3.6.1.4.1.318.1.1.25.1.4.1.13.1.1 = INTEGER: 1 iso.3.6.1.4.1.318.1.1.25.1.4.1.13.2.1 = INTEGER: 1 iso.3.6.1.4.1.318.1.1.25.1.4.1.14.1.1 = INTEGER: -1 iso.3.6.1.4.1.318.1.1.25.1.4.1.14.2.1 = INTEGER: -1 iso.3.6.1.4.1.318.1.1.25.1.4.1.15.1.1 = INTEGER: -1 iso.3.6.1.4.1.318.1.1.25.1.4.1.15.2.1 = INTEGER: -1 iso.3.6.1.4.1.318.1.1.25.1.4.1.16.1.1 = INTEGER: -1 iso.3.6.1.4.1.318.1.1.25.1.4.1.16.2.1 = INTEGER: -1 iso.3.6.1.4.1.318.1.1.25.1.4.1.17.1.1 = INTEGER: -1 iso.3.6.1.4.1.318.1.1.25.1.4.1.17.2.1 = INTEGER: -1 iso.3.6.1.4.1.318.1.1.25.1.4.1.18.1.1 = INTEGER: -1 iso.3.6.1.4.1.318.1.1.25.1.4.1.18.2.1 = INTEGER: -1 iso.3.6.1.4.1.318.1.1.25.1.4.1.19.1.1 = INTEGER: 1 iso.3.6.1.4.1.318.1.1.25.1.4.1.19.2.1 = INTEGER: 1 iso.3.6.1.4.1.318.1.1.25.1.4.1.20.1.1 = INTEGER: 1 iso.3.6.1.4.1.318.1.1.25.1.4.1.20.2.1 = INTEGER: 1 iso.3.6.1.4.1.318.1.1.25.1.4.1.21.1.1 = INTEGER: 1 iso.3.6.1.4.1.318.1.1.25.1.4.1.21.2.1 = INTEGER: 1 iso.3.6.1.4.1.318.1.1.25.1.4.1.22.1.1 = INTEGER: 1 iso.3.6.1.4.1.318.1.1.25.1.4.1.22.2.1 = INTEGER: 1
