Alerts not clearing
by Johnston, Tom 17 Aug '15

17 Aug '15

I’m going to piggy back off the issue of the Alerts not clearing. I’m getting the same issue and I’m pretty sure its SQL config related though I don’t know much past that. For example if I add a new device, I will get alerts for ports in the Admin up / physical down as I’m checking for that with an alert checker. That’s to be expected as I haven’t had a chance to turn off alerting on interfaces I don’t care about yet. Once it polls I turn off polling/alerting on interfaces (such as access ports) So if I go in and turn polling/alerting off on those interfaces I’d assume the alerts would clear. However the alerts persist and keep firing even if I have them turned off on those specific interfaces. I have figured out I can manually clear these alerts by restarting the mysql service. Here is part of the poller run (not sure if you want it all) ##### Completed polling run at 2015-08-17 11:34:51 ##### o Devices Polled 1 o Poller Time 7.877 secs o Memory usage 7.25MB (peak: 7.25MB) o MySQL Usage Cell[3/0.001s] Row[8/0.002s] Rows[52/0.02s] Column[2/0.001s] Update[20/0.014s] Insert[4/0.016s] Delete[0/0s] o RRDTool Usage update[29/0.033s] ——————— Output of my.cnf —————————— I have tweaked some of these in an effort to fix past and this current issue.

How to add support of new sensors for new (unknow) device
by Denis Zolotarev 17 Aug '15

17 Aug '15

Hello! I am very interested in adding support of new device series to Observium - NetPing (www.netping.ru) - devices for monitoring server rooms and remote power management. Could you please suggest how can I add support of the sensors for unknown (for Observium) devices? I have access to SMNP MIBs of this divices and can read value of any sensors via SNMP. For example I know the OID to read the temperature from one of the sensons: .1.3.6.1.4.1.25728.8800.1.1.2.1 Could you please explain how can I show this temperature on a graph in Observium? Thank you. -- Best Regards, Denis Zolotarev <http://google.com/+DenisZolotarev>

Hostname in generated graph image
by Simone Montagnani 17 Aug '15

17 Aug '15

Hi all, I've installed latest Observium community from a couple of months and it's working well. I need to use some graphs in other internal websites for monitoring, so I linked them directly using the URL of my observium server in the remote web server page. So, for example one link can appear like this: http://OBSERVIUM_SERVER_IP/graph.php?device=173&type=device_processor&legen… In this "mode" I can see the graph correctly but it's a simple blank page with the graph and legend but without hostname or any reference on it. Do you know is there is an option to add at graph.php to create hostname in the image? Generally: is there a syntax of all the options that we can pass to graph.php to get custom graphs, Regards, Simone

Alerts not clearing
by Robert Williams 17 Aug '15

17 Aug '15

Hi, We seem to have an issue with alerts not clearing (after they are OK) from the Alerts list. Example below shows a checked called “Hardware Fault” which matches Warnings, Alerts and Down status for devices. These items (two output phases) were above a threshold for a period over the weekend, but then went back below it and the event cleared. The device itself shows that the thresholds are OK now but it does list as “Status: Checks Failed” even though the values (and the graph) show it as OK / Green: [cid:image005.jpg@01D0D8D4.84525900] The actual item is here: [cid:image006.jpg@01D0D8D4.84525900] The event in the Main Alerts List is here: [cid:image007.jpg@01D0D8D4.84525900] The Alert Checker configuration is here: [cid:image008.jpg@01D0D8D4.84525900] Sorry for all the images, but it seems the best way to explain this particular issue! This is not the first time this has happened, last week we had 8 items stuck in an alert state, I had to delete the checked and clear the alert table for the so-called “failed” items to make them go away. However, now we have some new alerts they seem to be stuck in the same way. Any ideas? Cheers! Robert Williams Custodian Data Centre Email: Robert(a)CustodianDC.com http://www.CustodianDC.com

Incorrect memory graph for large RAM amount
by Louis Bailleul 14 Aug '15

14 Aug '15

Hi, Just discovered a weirdness when I added a server that has 3TB of RAM : the ucd_memory graph is totally messed up. It only displays negative amount of Cache/Shared buffers. The legend shows that it didn't handle the 3TB correctly. But it seems to be fine for the health/memory view where the correct amount is displayed everywhere. I have attached the debug output of the poller for this device. Best regards, Louis

Better performance on older hardware
by Louis Bailleul 14 Aug '15

14 Aug '15

Hi, I am in the process of qualifying some hardware to run Observium (planning to deploy it in about 25 locations). So I was trying to evaluate the hardware we currently have which consist of Dell R610 and IBM X3550. So we can gauge what we need. The R610 has : - 2x Intel X5660 (6 cores 2.8Ghz + hyperthreading) == total of 12 physical cores and 24 logical - 96Gb of DDR3 1333Mhz - 6x300GB 10K SAS configured as one raid1 of 2 disks for mysql and OS and a raid5 of 4 disks for rrds. - 1Gb network interface The X3550 has : - 2x Intel L5420 (4 cores 2.5Ghz) == total of 8 physical cores - 32Gb of DDR2 266Mhz - 2x200Gb 7.5K SATA configured as one for mysql and OS and one for rrds - 1 Gb network interface So reading this, it seems easy to guess which one should be faster. I am currently testing using : Observium CE 0.15.6.6430 OS Linux 2.6.32-358.14.1.el6.x86_64 [amd64] (CentOS 6.2) Apache 2.2.15 (CentOS) PHP 5.6.11 Python 2.6.6 MySQL 5.6.26-log SNMP NET-SNMP 5.5 RRDtool 1.4.9 From my testing, the poller perform a quite better on the R610 than on the X3550 : Polling the same 310 linux boxes (The slowest devices taking around 35 seconds) this gives an average of : - 8 threads : R610 : 169 seconds X3550 : 213 seconds - 12 threads : R610 : 69 seconds X3550 : 156 seconds - 24 threads R610 : 41 seconds X3550 : 107 seconds - 36 threads R610 : 41 seconds X3550 : 160 seconds - 64 threads R610 : 37 seconds X3550 : 225 seconds - 96 Threads R610 : 40 seconds X3550 : Still running Ok we clearly have a winner here. Bottom line for the poller, you can come close to the time taken by your slowest devices if you add more threads. But it seems that you need quite a few cores available to be able to increase the number of threads without decreasing the efficiency. This was kind of expected. Where the thing becomes weird it's on the web interface and especially the graph rendering : On average starting with a clear cache, the same Linux device page render (graphs included) consistently in about 1 second on the X3550 and in about 4 seconds on the R610 (screenshot attached). Where it became even worse : if you ask the X3550 to connect to the mysql database of the R610 and export the rrds of the R610 over NFS ... the X3550 still render the page faster (still around 1 second). Any guess on what is going on here ? It doesn't seem right that a machine that is definitely faster accessing mysql and updating rrds would be 4 times slower when rendering graphs. Best regards, Louis

Good morning all I have a new server setup with Centos 7 and Observium Everything looks good except I can't add any devices. I get an error that says it can't ping the device. I can ping when logged in from the terminal by IP and by Name. FPing also works from the console. IP tables and Firewall have been turned off for trouble shooting. I can add users etc. This is a replacement box so the devices are all configured correctly. Total loss here.

Re: [Observium] false device down alerts
by Rudolf Hoehler 13 Aug '15

13 Aug '15

Hello Sujith, When you set an alert you can set the number of polling runs before the alert actually fires. Under Alert Checkers set the "Alert Delay" for the checker to 3 or 4 and see if the results improve. If you are polling every minute you might start a polling run while the previous polling run is still happening. I would up this from 1 minute to about 2 or 3 minutes at least. Would be good to hear other comments on the fast polling time.
