Help with Custom Map Zenpack

November 16, 2009, 10:23 am

≪ Previous: VM Appliance 2.2 - ZenPack upgrade issue

I have been working on a zenpack that will allow a user to create arbitrary custom maps somewhat in the style of zabbix. Some of the features I have been aiming for:

Maps can have arbitrary images as backgrounds.
Maps can contain devices or submaps
ZenPack contains drag and drop editor
Nodes images can be set to user icons, and their labels can be positioned on any side of the icon, or ommitted entirely
Portlet allows you to navigate through the maps, and updates itself
A map's status is dependant on the status of any nodes or submaps on it.
Edges can be plain lines, or arrows showing the amount of bandwidth on the interface they represent

The actual implementation of the portlet and the map editor is fairly solid right now. We are currently monitoring about 1800 devices, most of which have placed into these hand-drawn maps. The individual maps load very quickly, and the portlet updates the map image seamlessly every 30 seconds.

I am not very familiar with zope, and the more I try to learn, the less it makes sense to me. There are a number of issues I am trying to solve that I would love some help with:

The map editor is implemented as a tab in the Locations section. Each Location has a custom_map property that contains all the information needed to draw a map. I seem unable to make the tab show up consistently though. When I set a recursive function to add it to all the Location objects, it works on some and not the others.
I would like to find a way to make the tab show up for new Locations as well. I have tried monkey patching the base Location as well as the class it derives from, but neither seems to work.
The map drawing code relies on PIL. There is a namespace conflict between one of the PIL modules (ImageFile) and zenoss. I had to modify PIL slightly to avoid the conflict. Is there some way I can include this with the zenpack? Or is there some other api I should be using to draw the images.

IP Service escalate count

≪ Previous: Help with Custom Map Zenpack

Is their a way to set an escalate count on an IP service monitor? e.g.

Im monitoring port 8080 with just the built in zenoss monitor that does
a port check. I can set the severity level when a connection to that
port fails, but I would like to set an initial severity level and an
escalate just like I can do on a data source. Thoughts?

Event Escalation based on Time

November 7, 2012, 9:11 pm

≫ Next: Zenoss + Apache mod_proxy

≪ Previous: IP Service escalate count

Hi All,

I want to escalate an event if it gets thrown up more than once in a 5 minute interval. e.g. the first event isn't necessarily a problem but a second event within 5 minutes would be and escalate accordingly.

I have played around with the event transform to escalate an event based on event counts (https://gist.github.com/1486570) and this seems to work for the most part.

However, because the first event sometimes happens overnight, we get false alarm when a second one appears sometime later and the first event hasn't aged yet. I don't want to put event aging too quickly. I tried creating an event transform that would be based on the firstTime attribute of an event but it looks like I can't reference this attribute in the transform.

Any pointers appreciated, thanks!

≪ Previous: Event Escalation based on Time

Following this article, I could redirect all of the requests sent to http://mydomain.com/zport/dmd to zenoss very well.

RewriteEngine On

RewriteRule ^/(.*) http://5.191.28.77:8080/VirtualHostBase/http/%{SERVER_NAME}:80/$1 [P,L]

But, I need to redirect to zenoss only the requests sent to http://mydomain.com/monitor

How can I do that? Is it possible using a Location tag?

Escalate Count: on /Perf/CPU

≫ Next: Beta AIX zenpack for Beta Zenoss

≪ Previous: IP Service escalate count

Hi,

We have enabled events on /Perf/CPU high thresholds in our environment.

Zenoss 3.2.1
Linux (x86_64) 2.6.32 (Linux nk-mgmt-dh-17 2.6.32-41-server #91-Ubuntu SMP Wed Jun 13 11:58:56 UTC 2012 x86_64)

But we do not want to get an event on every little performance spike:

I tried to set on both: Device(/Server/Linux) and WMIDevice(/Server/Windows) this.

(See scrots)

But still the events shows up after every little spike..

From what I read I thought that warning - 5 would take 5*5*3 minutes to create and show up that critical event?

Or am I being misled here by my own incompetence

Beta AIX zenpack for Beta Zenoss

May 9, 2008, 2:19 pm

≫ Next: WMI Non-Admin user not seeing all services

≪ Previous: Escalate Count: on /Perf/CPU

I've just added a beta version of an AIX Zenpack for the beta version of Zenoss. Perhaps "beta" is too strong of a recommendation for this ZenPack -- all I will guarantee is that it won't end all life on the planet (okay, maybe just Earth is safe... :)

This is an egg-style zenpack, so it most assuredly won't work with 2.1.3.

http://www.zenoss.com/community/wiki/user-contributed/

**Use this ZenPack only with a test Zenoss system to make sure that there's no possibility of messing up your other performance data.**

First, the bad news...

Known issues:
* requires SNMP version 3 with authentication off (ie SNMP v1 commands will work with this feature set). Description of modifications required in the description for the /devices/servers/AIX class.
* doesn't properly map to the manufacture links for any of the hardware found (eg disk, cpus)
* doesn't allow for re-exports of the ZenPack
* the performance collectors have no error checking and are written in bash and perl (Did I mention the word "beta" yet?)
* the performance collectors explicitly require that version 1 snmpwalk and snmpget work, and won't accept other credential info
* filesystem events don't insert the name of the filesystem
* sanity checks in the modelers seem to want too much sanity, as they *seem* to sometimes prevent modeling (aka discovery) from gathering all information. On the plus side, the sanity checking does prevent Zenoss from blowing away previous modelled device info when it can't talk to the SNMP agents or the machine is down. :)
* the AIXBase modeler still doesn't seem to properly identify the hardware model and update the correct spot for the hardware. The serial number does appear to be updated correctly for the hardware, however.
* doesn't show the per-processor statistics, only a total averaged number. In addition, the MIB doesn't update the statistics all that frequently (I might have missed a setting that can up the polling on CPU usage), so it may even be fantastically wrong.

.. and now the good news:

Features:
* uses standard IBM AIX snmpd services. No net-snmp daemons required, no other packages to install.
* adds subclasses for /devices/servers/AIX, with further subclasses for LPARs and VIO servers. Adds a token link into /devices/server/Linux/HMC with a customized zLink so that it's (perhaps?) easier to get to the HMC console.
* (YMMV) discovers memory, paging space, processors, disks, adapters and filesystems. NB: FRU information and model numbers would (I *think*) require updates to other ZenModel relationships, which would need to be in the base Zenoss.
* has a copy of the AIX MIB (from the samples directory) and cleaned up version of the xmtopas-generated MIB (the MIB it generates is, to be polite, syntactically challenged. It may also be plain wrong in places. :)
* allows for a lot more performance statistics to be gathered

While fixes are especially welcome, other feedback is also appreciated. :)

Thank you,

kells

Future possibilites:
Note that storage-related info such as VG + LV + filesystem + MPIO path + LUN ID mapping will require ZenModel relationships to be created, which will require time. This would be useful to be able to create a report to determine (for example) which filesystems would be affected by an outage of which SAN storage system. Some info may also not be available through SNMP.

The VIO mapping of virtual adapters to physical adapters and LUN assignments might be impossible through SNMP. I have written Perl scripts to do end-to-end storage allocation (optimized) / deallocation / management from a DS81k through VIOs to an AIX LPAR so I know how to do it, but I'm not at liberty to share that code, much less contribute it.

happy If anyone else has thoughts about implementing something, please let me know.
