I have a weird error when click on graphs for all Windows hosts.

pythonThresholdException User-supplied Python expression (here.getTotalBlocks() * .9) for maximum value caused error: ['usedBlocks_usedBlocks']

By default when you assign a host to FileSystem template (in our environment it's always Windows for whatever reason), there is one graph for storage usage utilization. It has a formula in the maximum threshold value which is referenced in the error.

Any ideas?

SNMP is working. I've tested usedBlocks OID.

Thank you.

A couple of possible things here...

You say "when you assign a host to FileSystem template"...... - the FileSystem template is a COMPONENT template not a device template, so you should not be binding this template manually - it should bind automatically.  If you see FileSystem as a template bound to the device then unbind it. (BTW - what version of Zenoss are you on??).


You have obviously checked the SNMP connectivity to your Windows targets but could you check each of the OIDs that are specified in the FileSystem template.  I've seen some Windows SNMP agents that provide some parts of the file system host resources MIB, but not all the expected data.

Cheers,
Jane

Yasha:

Change the threshold to:  ((here.getTotalBlocks() or 1) * .9). This will advert the 'Python experssion' error.

In the /Perf/FileSystem transform add a check for if getTotalBlocks() is None or < some number and to rewrite the event in such case to tell you that the TotalBlocks has not been modeled for that device. This will let you know what devices need their filesystem information remodled/fixed, etc.


Chances are if this value isn't filled its due to a modeler that hasn't run or is malfunctioning.

Thank you for responding guys.

SNMP connectivity does work to this windows box except that it doesnt collect everything. I did the walk and it gave me some info.
I am using 3.2.0 zenoss.

Shane, I've tried modifying that formula but no luck. Error is still there. I've restarted service, deleted RRD files and no luck. Maybe something else needs to be done.

It feels like there is no data being collected for that value so it blows up.


Thanks.

When I do snmpwalk it retuns everything. Interesting fact. By default snmpwalk in zenoss appends "system" at the end of command. It will almost return nothing with that in there. If I do a snmpwalk from console without that "system" entry, it gives me everything.

Also, I do a test on UsedBlocks DataPoints and it returns to me a list of 4 entries.
BTW, I've tried to just use one still no luck.

Thanks.

Shane,

Are you talking about just modeling the device?
I am having hard time logging into the console with zenoss username. I believe it doesnt have password by default.
If you need to see the output of model the device through the gui, here it is:

snmpwalk works just fine.

Here is the issue. The community string has $ sign. When I run snmpwalk in console I use \$

In properties of object in zenoss I had \ as well. So I have removed it and modeler works fine. Here is the output:

So even if I specify escape character (ie \)?

I dont have an option of changing it. That's the problem.
What about SNMP v3? Do you know how to configure it in windows?
If I use that, then I wont need a community string. User account with pass can be created by me.

Thanks.

It looks like Windows natively doesnt support v3.

What do you think about upgrading zenoss to 3.2.1 from our version 3.2.0?

I don't think theres a way to make zenperfsnmp handle those characters that's easy to implement. I think you're right, Windows doesn't do v3 OOB. The only real option would be to convert all the templates to zencommand datasources, but, this is easier said than done. Is it really not an option to strip out the $?

That's what happens when you are not in charge of the system. For others $ doesnt cause a problem to have snmp monitoring. For zenoss it does.

I am trying to get another community string created. It seems that Windows can have multiple ones. That hopefully should solve the problem.

Thanks for your help.

When you click on file systems under components, all of the data is there. Used space info, and etc.

Something is not right withat threshold UsedBlocks thingy.

I think it is not the modeler but the perf one that is having problems.
I've removed escape character from config and modeler is working but when I test OIDs it wont work since it doesnt have escape character.

So if you remove the escape it'll model and apply changes but then won't collect? In that case it sounds like zenperfsnmp requires the escape character or can't handle it at all. Very odd.

Yes. So I've removed escape character from configuration properties and modeler goes through (I've showed you the output. the second one). Performance in graphs, it seems, never worked.

What's weird is that graphs in Components sections collecting data and graphing ok. Even that same usedblocks data in File Systems sections.

So I am confused. Isn't that being done by perf.?

I am starting to feel like I am misunderstanding myself :)

It's weird but File Systems (under Components) graph has threshold configured as well. It's using 90 (I assume %).
It shows just fine.

The problematic one comes from Monitoring Template - FileSystem (/Server)
If I change threshold from that here.totalblocks to some number, it gives another error.
rpnThresholdException The following RPN exception is from user-supplied code

It feels like that particular monitoring template is messed up or something.

THanks.

I'm thinking that some device has an invalid entry for totalblocks. Can you post the entire alert?

For the heck of it change the threshold value to '(here.getTotalBlocks() or 1) * .9. This will default to a value of 1 in cases where here.getTotalBlocks() returns nothing. If the message goes away we can conclude that obj.totalBlocks isn't getting filled and start looking there.

What's interesting is that if I go to File Systems under Components, it shows the same graph there.
But in Graphs section (where I get this error) it doesnt show.
Weird.

In zendmd do

d=dmd.Devices.findDevice('name of one of the problem devices')
d.id

if the name of the device is returned, continue.

for fs in d.os.filesystems():
    try:
       fs.id
       fs.getTotalBlocks()
    except:
       print fs.id + 'is a problem'

{press enter twice}

Exmaple output:
16162687.0
'boot'
101086.0
'opt_zenoss'
52443590.0

If any say 'is a problem' let me know.

Zendmd must be run as the zenoss user. Never run or start any zenoss executables as anything other than zenoss. Doing so will help prevent permission problems :)

I've tried a few but all return data.

You see the weird part is that File Systems graphs in Components section does show the same graph.

It's something with that default graph under Graphs section. Anymore ideas?

It didnt work, Shane.

I got errors when doing post-upgrade stuff.

One warning:

Daemon: zeoctl /opt/zenoss/bin/zenoss: line 130: /opt/zenoss/bin/zeoctl: Permission denied

And then alot of these:         

Testing for the pre-upgrade ZenPack...
WARNING:ZEO.zrpc:(4156) CW: error connecting to ('localhost', 8100): ECONNREFUSED

It would just repeat these non stop on 3-4 second interval unless I break.

Any ideas?

I am thinking about installing brand new VM (3.2.1) and doing backup/restore

Yasha:

Ah gotcha. I didn't realize you were using the virtual appliance. As root cd /opt/zenoss/bin and try ./zenoss_upgrade_pre.

I'm curious if its a problem with the env or service.

I ran that command before installing new RPM.
Here is the output.

That command is essentially the script that gets run by service post upgrade of zenoss during service zenoss start. After installing the updated rpm, did you try that command?

I believe it runs automatically when you try to start the service after RPM install.
I've seen this output. Almost right after "functions converted", I get that warning about permission denied.

Shane,

So I've tried to install newer version of zenoss virtual appliance, backing up my 3.2.0 version and restoring it to 3.2.1.

I got the following error after running zenmigrate after the restore.

ValueError: Non-zero version length. Versions aren't supported.
Have you seen this problem before?

Thanks.

Nice :)
I think original Zenoss (3.2.0) that I have installed, was not a virtual appliance. I ran zenbackup with sql and file switches. Then I've downloaded 3.2.1 virtual appliance and doing restore and zenmigrate in there.

I read some stuff online and somebody else had similar issue but in older version of zenoss. They were saying that "zodb versions" of previous installs are still stored and it caused this error.

When I've installed 3.2.0 version I had to do the same approach (ie backup, restore, migrate) from previous version (I think it was 3.0.0 or so).

Hopefully this information can be helpful.

Thanks.

You are aware that you can only successfully restore a Zenoss backup to the same version of Zenoss right? So if you have a backup of 3.2.0, you'll need to restore it to 3.2.0...

Running zenmigrate --list under zenoss user account doesnt provide different output result.

Should I run that when services are stopped or started?

zeoctl must state that zeo is running at a minimum for zenmigrate to run. if you run zeoctl status as the zenoss user and it says its running, try doing a zeoctl restart then the zenmigrate --list again

More updates.

I finally got the restore and migrate to work.
I think before the restore, I need to access the web gui atleast once to set admin pass and create a user.
After that zeoctl was starting and restore and zenmigrate worked.

Now, my web gui is not coming up.  :)

I've noticed that it is not using appache (ie httpd service). Where is the config for the web interface?

Thanks.

Nice. It uses Zope. Zope can be started and stopped by zopectl. $ZENHOME/etc/zope.conf is where the config for zope resides.

Ok. So I was able to get the web gui to come up but the original error is still there.

This makes me believe something is not right in the data. But at the same time why does this happen for ALL windows based objects???

Is there a way to debug this somehow?

Thanks for your help Shane.

Shane,

I have started debuging the graph and here is what I have.
UsedBlocks data source points at the list of file systems. So if you have more than one, you will have a list. I've tried switching to just .1.
Next, I've taken out High Usage Threshold out of the picture. I am trying to get Used Blocks to display percentage.
In the properties of UsedBlocks data point it has the following RPN:
${here/getTotalBlocks},/,100,*

It is not working. Do you see anything wrong with it?
As far as I understand it should divide current value by total blocks and then multiple by 100 to get percentage.

I get the following error while rendering the graph.
error: invalid rpn expression in: usedBlocks-raw,(Tales expression error)

So it looks like I was able to figure out the problem.
If anybody is interested here is what happened.

After plenty of troubleshooting I have decided to install Zenoss VM Appliance from scratch and add all of my devices and configuration manually. After doing so I've noticed why it was not working on my old install. Windows devices had an additional monitoring template assigned to them by "somebody". It was not meant for it so it had issues described in previous posts. By default that problematic template is not part of Windows devices.

Problem solved.

According to http://community.zenoss.org/docs/DOC-4752 http://community.zenoss.org/docs/DOC-4752 documentation, there is a command called zenmigrate which is used when using backup/restore on  different versions.

-----
If you use these tools to go from an older version to a newer version, you should run *zenmigrate* after the restore operation.
