HTTP/1.0 500 after upgrading to latest version 12324

Hello, We have just upgraded our subscription edition to the latest 12324 (from a pretty old version). But the GUI is not accessible anymore afterwards, with HTTP/1.0 500 errors. Restarting ‘httpd’ (showing ‘active (running)’) and reboot the server doesn’t help. Any suggestions how we can fix it or troubleshoot further? Thanks. - Gordon

Show port descriptions also on Ports -> Map view

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 08 Oct '22

08 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

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.
