SNMP link up automation

Hello everyone,

 

I am sorry if this is a repost or worded poorly.

 

We currently have an implementation of ONMS version 1.8.1 it was installed some time ago by and employee who is no longer with us and there is little to no documentation on the system. I finally have the time to work on a reinstall of the system. I am not going to upgrade as I think that he wrote a bunch of customizations to the system and if it breaks I have nothing to really fall back on.

 

I have some cisco 6500s and 7200s that I have that I am testing this new implementation on. I have created the requisition groups and added one of the devices to this group. I have a policy that removes Null and admin down interfaces that I am only dealing with interfaces that are actually in service.

 

We on the 7200’s a bunch of serial interfaces some of them have IP addresses others do not (members of multilink). I have the device send linkup/linkdown traps to the ONMS box that way I do not have to rely on ICMP. The problem with ICMP is it will not tell me when a link in a multilink bundle has gone down.

 

I see the traps coming and I have created a notification for when a line goes down. The issue I am having now is that when the up trap comes in the notification is not cleared. From what I can fathom out about automations is that I cannot use the %params% in the event to identify the specific interface notice and auto acknowledge it.

 

I edited the notification to so that the numericmsg field has the nodeid and the %params[# <at> ]% but when it comes to auto acknowledging based on that it seems that that data has not yet been created in the database to match on that field.

 

I have been looking at the translations to see if the translations can change the interface parameter on the even to be the interface name vs the IP of the device sending the trap.

 

I get the feeling this is something very simple that an NMS system should do and I either overcomplicating the matter.

 

The end result of this is I want to make sure that if a line just flaps that the notification will be sent and then when it comes back suddenly the notification is  auto-acknowledged and the RESOLVED email is sent.

 

This way I will only escalate the line down to my support team if it has been down for more than a certain time. Also if it is after hours I can change the parameters so that there is a higher tolerance for a downed lines and the afterhours team can be notified on a different schedule.

 

Right now I have the link down and the link up notifications in my outstanding notifications.

 

Any help on this issue will be greatly appreciated. (sorry if I rambled)

FYI: [Summary] Documentation Meetup cw30/2014

Hi Guys,

we had our second bi-weekly doc meeting this evening. We talked about the following topics:

Current status quo
------------------------
- We aimed for an issue driven GitHub Pull requests workflow
 Special thanks to Ian and Cyrille who helped working out a pull-request / patch based GitHub workflow
- Branches are named in the following pattern <NMS-number_docs_MonitorName>
- During the first phase we started a draft for a documentation guideline[1] which should help to get you over the hump. It tackles different topics, like formatting conventions and even a short introduction with examples how to use AsciiDoc.
- Pull requests are made against the opennms repository branch “development/docs”
- Pull request is reviewed by second person and after review phase merged to “development/docs”
- Ben configured OpenNMS Bamboo to pick up merged pull requests, they will be compiled and deployed doc to a public location[3]
- The Wiki page structure for “How to contribute docs”[4] to solve the first entry level questions is improved. The structure is much clearer now.
- We have a Wiki template[5] for monitors which are currently in progress and are migrated to the official doc
- Status “Resolved” is used as merged to “development/docs” and published
- Status “Closed” is used as camera ready and reviewed for conventions and language issues
- Currently: 17 of 71 monitors are documented[2]
- We where able to get the meeting down from 2h to 1.5h :D

Issues and problems
---------------------------
- It is not possible to assign a JIRA task. You need special permissions to assign external user to tasks. So they can’t start a task as in progress
- Links are inconsistent on the OpenNMS.org events section[6] and the wiki events section[7]
- We talked about detectors and monitor documentation. We can remove detector/capsd and other behaviours from the monitor documentation. Creating similar section for detectors and use links if a detector exist for a given monitor
- Problems dealing with JIRA issues is a higher barrier. Evaluation if there is a possibility for an easy to use simple web form creating an issue in JIRA
- Language support in docs: There are possibilities but not focused right now.
- Embedding external content in the wiki has some security implications, XSS etc. In longterm the Wiki documentation should be slimmed down.
- Having a stable links to versions of documentation for external links, 
http://docs.opennms.org/guide-admin/stable —> http://docs.opennms.org/guide-admin/1.12.8
http://docs.opennms.org/guide-admin/testing —> http://docs.opennms.org/guide-admin/1.12.9
http://docs.opennms.org/guide-admin/unstable —> http://docs.opennms.org/guide-admin/1.13.3
http://docs.opennms.org/guide-admin/snapshot —> http://docs.opennms.org/guide-admin/1.13.4
- We haven’t checked homework[8]

Goals for the next 2 weeks
-----------------------------------
- Installing the categories plugin in MediaWiki on opennms.org
- Finding a way improving the JIRA workflow for external users, assignment, unassignment, start in progress etc.
- Improve documentation guide with describing the GitHub pull request workflow[9]
- Documentation more monitors, what done is, is done [2]
- Improving documentation guide from native language perspective (no JIRA issue yet)
- Review already documented monitors (no JIRA issue yet)

If there is something missing, just reply to the mail on the opennms-docs list
The procedure for cw32 is the same as usual. I’ll send out a doodle to opennms-docs and opennms-discuss

Thank you guys for spending your time and have a nice week.

OpenNMS Training: 11-15 August

Gang:

Sorry for the interruption ...

Just a reminder that we do offer formal training on OpenNMS about once a
quarter, and the next class will be from 11-15 August here in
metropolitan Pittsboro, NC, USA.

http://www.opennms.com/training/

OpenNMS is pretty darn powerful and it can take awhile to get your brain
around it, so we hope to speed up that process with our classes. Plus,
they tend to be a lot of fun.

If you are interested and have any questions, please feel free to
contact me off-list.

... now back to your usual OpenNMS-ness

ACL's and Categories

All,

I was able to get ACL’s working for 90% of what we need it for using the following URL:  http://www.opennms.com/this-week-in-opennms-acls-the-new-hotness/

There is one issue we’re having, and that is why I am sending this mail.  We also use Categories (categories.xml) on the main page to display our servers by functional business group.   Is there a way to apply ACL’s/Filters to the categories.xml?

OpenNMS Version:  1.10.7
OS Version:   RHEL 5.8

Example from categories.xml:

            <category>
                <label><![CDATA[PECO_DA]]></label>
                <comment>PECO_DA</comment>
                <normal>99.99</normal>
                <warning>97</warning>
                <service>ICMP</service>
                <rule><![CDATA[catincPECO_DA]]></rule>
            </category>

The goal is to show the above category ONLY if the logged in user is = “peco”, for example.   It would not display any other categories to user “peco”.

Any/all help is appreciated.

Release Notes converted to AsciiDoc
http://docs.opennms.org/releasenotes/1.13.4-SNAPSHOT/

Administrators Guide where we document the monitors
http://docs.opennms.org/guide-admin/1.13.4-SNAPSHOT/

Thanks for all the work

no interface data when debugging collectd (1.12.5)

Hi Folks,

just for your information:

There were some discussions about missing data in graphs. We experienced this with OpenNMS Version1.12.5
and found out that it was related with debugging collectd/thresholds. When we enable DEBUG logging level
for those two daemons we don't get any snmp data in the rrd files, while thresholding still works, e.g. data
gets collected. After setting the logging level to WARN everything works as normal again.

Un-clearing alarming on new event

I've searched and tried many different config's in vacuumd-config to get 
alarms to unclear when a new event is raised for the same alarm.

The issue is when an alarm has been cleared and is awaiting deletion by an 
automation, if the same alarm is received again in this time, the severity 
stays as cleared instead of changing to the events severity and only the count 
is increased.

The 'resetSeverity' action never seems to catch the new event before the alarm 
is deleted.  I've tried adjusting the automation interval for this and the SQL 
also.

The other thing with using an automation to unclear an alarm is if I manually 
clear an alarm rather than allow a resolution to clear it, the 
'lastautomationtime' field for the alarm isn't updated - again skipping the 
'resetSeverity' action.

Is there config or code somewhere that can be adjusted to force updating the 
severity of an existing alarm at the same time the count is increased when the 
corresponding event is received again.

Thanks,
Matt

yum repo for rhel7/centos7?

Are you planning to support el7 anytime soon?   Should be
approximately the same as Fedora19 w/systemd to start things.
