It requires SNMP contexts, which are a pain. We've been wary of using them because then can cause huge poller delays on devices which don't support them. Adam.

We could use device attributes to disable it if it fails. But that might trigger if the device went down mid-poll :-\ Adam.

ARP Table empty
by Tobias Brunner 15 Feb '13

15 Feb '13

Hi list, The "ARP Table" on all ports is empty (f.e. /device/device=95/tab=port/port=13844/view=arp/), I'm wondering why... Shouldn't there be listed all MAC addresses in the MAC address table ("show mac address-table")? Or is this really just the MAC<->IP table? If yes, are MAC addresses tables saved in the Observium database to see which MAC address is on which switchport? Looking at the "ARP Table" from all Ports (f.e. /device/device=95/tab=ports/view=arp/) there are MAC adresses which belongs to an IP address. All devices are Cisco Switches or Brocade Router.

Hi, I’ve been evaluating observium for almost 6 months now and in general I’m really happy J. But I read in the manual that nfsen can be integrated with nfsen data, I’ve followed the manual but still nfsen data not shown in observium. Is there anything I missed? Thanks. Rgds, -dewo-

speed up the poller with poller-wrapper.py
by Job Snijders 14 Feb '13

14 Feb '13

Hi all, Are you not sleeping well because there are gaps in your graphs? Do you feel like your observium poller isn't putting enough effort into its sole task of polling every device and completing that task in less than 5 minutes? Fear not, a dirty script called "poller-wrapper.py" is here! I wrote a small wrapper that has a slightly more modern approach to getting things done. An issue with the multiple poller instances approach[1] is that when a single instance has to poll a few slow devices, that single instance cannot finish its work in time, while the instances that already finished their portion of the work will not 'help' the instance with the slow devices. This wrapper script will create a Queue with all the work that has to be done and launch a number of threads which will take work from the Queue until the queue is empty. This distributes the workload over the instances move evenly, thus improving performance and thus making it more likely to finish all the polling work within 5 minutes. You can easily test what number of threads works well with your environment by running the script a few times manually, here I run the script with 32 threads: root@observium:/opt/observium# python poller-wrapper.py 32 worker Thread-23 finished device 75 in 9 seconds worker Thread-25 finished device 84 in 2 seconds worker Thread-21 finished device 81 in 5 seconds <SNIP> worker Thread-23 finished device 98 in 81 seconds worker Thread-3 finished device 94 in 116 seconds worker Thread-32 finished device 93 in 126 seconds poller-wrapper polled 130 devices in 179 seconds with 32 workers root@observium:/opt/observium# Source: ------- URL: http://noc.as5580.net/~job/observium-poller-wrapper.py.txt Installation: ------------- cd /opt/observium wget http://noc.as5580.net/~job/observium-poller-wrapper.py.txt -O poller-wrapper.py Now open poller-wrapper.py with a text editor to change the database username & password. open /etc/cron.d/observium and replace this line: */5 * * * * root /opt/observium/poller.php -h all >> /dev/null 2>&1 with something like this: */5 * * * * root python /opt/observium/poller-wrapper.py 16 >> /dev/null 2>&1 Kind regards, Job Snijders Atrato IP Networks [1] http://www.observium.org/wiki/Performance_tuning#Multiple_poller_instances

Hello, I just did a new installation of observium in our network and I pretty much like it. Unfortunately, I do have the problem, that all graphs are empty while f.ex. the temperature readings on the device overview page are fine. As I figured, the RRD files seem the have only "NaN" values: <snip>  <row><v>NaN</v><v>NaN</v><v>NaN</v><v>N aN</v><v>NaN</v><v>NaN</v><v>NaN</v><v>NaN</v><v>NaN</v><v>NaN</v><v>NaN</v><v>NaN</v><v>NaN</v><v>NaN</v><v> NaN</v></row>  <row><v>NaN</v><v>NaN</v><v>NaN</v><v>N aN</v><v>NaN</v><v>NaN</v><v>NaN</v><v>NaN</v><v>NaN</v><v>NaN</v><v>NaN</v><v>NaN</v><v>NaN</v><v>NaN</v><v> NaN</v></row> </snip> I am running Observium 0.13.2.3586 with RRDtool 1.4.7 on 2.6.18-348.1.1.el5.centos.plusPAE. Any help is appreciated. Thank you in advance. Kind regards, Julian
