Hi All. Thank you for the reply. I do agree that this information is not published via snmp. Maybe it will be the first system to use telnet or ssh and do some text parsing. Its also a lot more reliable. That can be a great thing. Thanks again David.

(You can search for it on the top right) 2) Click on the "Ports" tab. 3) If this is a router, there will be a tab called "ARP/NDP Table", this is IPv4 and IPv6 mapping of MAC address to IP address. If this device was only a layer-2 switch, then this tab would not be displayed. 4) There is a tab called "FDB Table", this is the mapping of MAC address to switchport. (I have always called this the CAM table). Due to the functionality of broadcasts, this will show every device in the same VLAN (the MAC address is seen on switch uplinks) However, I wish there was a node lookup tool that showed which switchport a computer was plugged into. We should be able to identify the interface closest to the computer by removing all interfaces that are CDP/LLDP neighbors with another known network device. Does this make sense?

Maybe I got it Wrong.
by Dudu 11 Sep '14

11 Sep '14

Hi All, I'm new here and I'm not sure about the port view. I can see the neighbours and computers on the vlan on right side , the command looks like show ip arp Maybe it's better to map the computer to the port itself? sh mac address-table So out of the box we will know which server is connected to which port. That could help to find VM's as well. Many Thanks David.

Re: [Observium] how to make observium not to poll certain mibs

I tried that. But seems only a few module are listed there. I think if I disable any of them, a big class of monitors would be disabled with it. I am looking for a way to disable certain mib/objects. Thanks a lot. Would removing/commenting out those objects from the mib file help?

The ports on the switches doesn't seems to display correct network throughput
by Arya, Renuka [BSD] - MED 10 Sep '14

10 Sep '14

Hi Team, I installed Observium recently. It seems to be working just fine. However, I do see discrepancies in the throughput result. When I run a network performance tool (Nuttcp) on one of the server and monitor the corresponding port on the switch through observium. I observe that the the server is generating around 9.8 Gbps data. If I check the ports directly on the switch I see same thing (~9.8 Gbps) but when I see in through observium on the corresponding port , I see frequent spikes to 12 - 15 Gbps. I am not sure why I am seeing these high value because the NICs on servers are having a 10 G NICs and I never see anything higher than 10 Gbps on server or on the port on the switch. But the real time graphs on Observium shows the spikes of around 12 - 15 Gbps. I would be really glad if you help me on this. I really like the tool but the discrepancy in the throughput result is kind of driving me crazy. Thanks!

email alerts
by Zhenhui Liang 10 Sep '14

10 Sep '14

Hi, All I tired many ways to make email working. But seems to be out of luck. >From linux command line, mail prove to be work on either local sendmail/postfix or via external smtp server. Php test email works either way as well. But observium seems not able to generate any alert email. A tcpdump session would not capture any email data as well when my configured alert checker fires off an alert. Seems from config.php, I need to configure $config['alerts']['alerter']['default']['descr'] = "Observium Email Alert"; $config['alerts']['alerter']['default']['type'] = "email"; $config['alerts']['alerter']['default']['contact'] = “zliang(a)xxxx.com"; $config['alerts']['alerter']['default']['enable'] = TRUE; $config['email_from'] = “observium(a)xxxxxx.com"; $config['email_backend'] = "mail"; $config['email_smtp_host'] = 'localhost’; Also tried $config['email']['from'] = “observium(a)xxx.com"; $config['email']['backend'] = "mail"; $config['email']['smtp_host'] = 'localhost'; $config['email']['default_only'] = 'true'; $config['email']['smtp_secure'] = 'false’; And $config['email']['from'] = “observium(a)mydomain.com"; $config['email']['backend'] = “smtp"; $config['email']['smtp_host'] = ’smtp.mydomain.com'; $config['email']['default_only'] = 'true'; $config['email']['smtp_secure'] = 'false’; None of those combination of configs works. It looks like we are deprecate old format of $config['email_from’] to $config[‘email’]['from’] style? With later format, from global settings, I could see my change taking effect. But using the old format, some values got updated, some not. But nevertheless, email were never sent out. Please advise. I am using code version of Observium 0.14.9.5798 Apache 2.2.15 (CentOS) PHP 5.3.3 MySQL 5.1.66 SNMP NET-SNMP version: 5.5 RRDtool 1.3.8

how to make observium not to poll certain mibs
by Zhenhui Liang 09 Sep '14

09 Sep '14

Hi, Sorry if this has been answered. But I didn’t find the answer in doing search. So we have a router bug of memory leak core-dump which was caused by observium trying to do snmpwalk against a certain mib. Vendor advise us to upgrade the code to latest, which we can’t do without significant amount of coordination. So I am trying to figure out how to make observium not to poll it. didn’t find from gui. If I delete the mib definition from the mibs/ sub dir, would that be enough? Thanks a lot.

FW: FTOS 9.4 not working properly with Observium whereas 8.3.12.0 for Force10 switches
by Arya, Renuka [BSD] - MED 09 Sep '14

09 Sep '14

Hi Team, I recently installed Obervium I am in process of adding my switch devices to Observium network monitoring tool. It seems that my Force10 S4810 switch with FTOS 8.3.12.0 displays correct graphs whereas the Force10 S4810 switches with FTOS 9.4 doesn't display graphs correctly.It works partially, but doesn't display a lot of other information. The website http://www.observium.org/wiki/Supported_Devices says they have tested FTOS till 8.2.1.2 and I can see it works fine at least till 8.3.12.0. So Iam not sure what should be expected for higher version of FTOS. It works just fine with Arista OS 4.13.6F I'll be really glad if you can look into this. Thanks!

alert checker based on a specific mib value?
by Zhenhui Liang 09 Sep '14

09 Sep '14

Hi, I am trying the enterprise observium version now for the alert checkers. I understand that we could add checkers based on existing conditions and metics listed on http://www.observium.org/wiki/Alerting_Metrics_and_Attributes But say, if I want to alert on another mib value not listed here, is there currently a way to do so? for instance, I have this mib listed under mibs/PAN-MIB-MODULES panSessionActive OBJECT-TYPE SYNTAX Integer32 MAX-ACCESS read-only STATUS current DESCRIPTION "Total number of active sessions." ::= { panSession 3 } Can I add an alert checker to put condition as panSessionActive gt 100000 ? I tried, but seems not able to. Is there a special way to do so? Thanks a lot. —Zhenhui Liang
