Technical Resources : VMware vSphere Health Check Report v1.3 : Comments

RE: VMware vSphere Health Check Report v1.3

I've noted that with the vMA on ESX3.5U4 I get an error with the .9.4 script you have also graced us with. Is it even worth an attempt to try this script (with the vMA) on older hosts?

I am assuming the it's a VIMA/.9.4/ESX3.5.x and vMA/1.2/vSphere kind of relationship....

If you look at the requirements in the documentation you'll see one is for pre-vSphere and the other is for vSphere.

The relationship is the following:

VIMA 1.0 + ESX(i) 3.5u2+ = VMware Health Check Report v0.9.4
vMA 4.0 + ESX(i) 4.0+ = VMware vSphere Health Check Report v1.3

How to scheduler this report on daily basis and email it automatically?

Thanks in advance.

If you're launching it from a Windows box I would guess that you could do it as a couple of scheduled tasks (1> generate 2> email).

If you're doing it from the vMA it would be a cron job.

Maybe someone with direct experience will chime in, but examples of both should be on the interwebs.

What an awesome script! If anyone knows how to schedule this as a Scheduled Task in Windows 2008 please post it. It would help greatly!

vancod — Tue, 06 Oct 2009 13:36:40 GMT

@IPF - I've seen other scripts here that do this, I just don't recall which off top of my head. I'm sure a search will get you an answer...

I've got as far as creating a .bat file with the following:

START "C:\Program Files\VMware\VMware vSphere CLI\Perl\bin\perl.exe" "C:\Scripts\vmwarevSphereHealthCheck.pl" --server SERVER --username USERNAME --password PASSWORD --type vcenter"

When I run the .bat file it runs great. As a scheduled task...nothing happens. I've tried just the command in the scheduled task as well...nothing.

IPF — Wed, 07 Oct 2009 14:01:47 GMT

There has to be someone who has created a scheduled task? Anyone?

I so have to learn to copy my comments into my paste buffer before trying to hit submit on these sh*t forums... I lost a much longer post

Anyway -
Remove the "START"

Pass a "-- report" option - your command just send the output to null space

Start your task or specify your file output path as required or you'll be hunting for the result.

William - I use the vMA mostly, but am getting wonky results

"Can't use an undefined value as an ARRAY reference at ./vmwarevSphereHealthCheck.pl line 1114."

my licensing data is screwy (shows negatives)
the "Features" section has headers on top and sides, but no actual table data at all (not even empty cells)
my cluster hosts show up fine but my stand-alone host is ignored (I think this was a legacy known issue?)

Please provide the exact syntax you're using with all the command line flags to help me better understand your issue.

Are you using vMA 4.0? and what is your environment like both vCenter and ESX(i) systems? build/versions?

Regarding line #1114, this refers to the following:

my $luns = $host->config->storageDevice->scsiLun;
      foreach (sort {$a->canonicalName cmp $b->canonicalName} @$luns) {

If you don't have any LUN(s) or have only one LUN, it should still process. I'm not sure why it's not.

Syntax (used on both my XP-based perl toolkit and the vMA):
vmwarevSphereHealthCheck.pl" --server 192.168.2.160 --username Administrator --password xxxxxx --type vcenter --report vCenter.html

The vMA:

it is the 4.0 release
there's a security patch I have yet to apply, but is otherwise up-to-date / current

Env:
(these are all "real" machines - no VMs / tomfoolery)
vSphere vCenter (also has FUNCTIONING legacy license server, it was an upgrade from 2.5)
Single vSphere ESXi host that is stand-alone
Pair of vSPhere hosts (one ESX, one ESXi) in a cluster

all are current (patched)

All have single active GigE connection at present

All use a single NFS share (RHEL based server should it matter)

I have a couple of licenses at present and can detail if required.

I will send you a link to the output via PM

With the information you've provided, here is what I'm thinking:

Is the vCenter fully managing all ESX(i) 4.0 hosts? If so, then the licensing server from VI3.5 might be what's causing the issue since the licensing portion of the API has significantly changed between VI and vSphere ... which could explain why it's off. If you don't for see needing the license server, can you try uninstalling and re-running the report to see if license output is fixed? This was one of the main reason I had two separate health check scripts for VI 3.5 and vSphere 4.0 due to the differences in the APIs.

Regarding the stand alone host, if it's not part of a vCenter cluster, it will not be caught by the script and that is a requirement. How is your ESX(i) host connected to your vCenter? Can you provide me with the inventory breakdown (e.g. hosta/b are in cluster1 and hostc is in cluster/etc?)

At present, yes, vCenter is managing 4.0 hosts only. Until only a couple days ago I maintained a 3.5 host. Customer requirement (I'm a working consultant by trade) will likely mean another 3.5 host sooner or later.

However, I can test with the licensing server off (is uninstalling really required?) I will say that I have a number of customers that will have both legacy and vSphere based licensing simply because of the upgrade process and internal requirement - I hope the script can be made happy by just killing the legacy service for a few ticks. I will test this tomorrow as time permits.

Yes - my one host is, at present, outside a cluster, and I thought I recalled that this was a limitation / requirement of the script. SO basically I have hast a & b in a cluster, and host c is "a loner". But again, this changes frequently as required.

William,

When I run the script with "--type host" and have SNMP enabled on the ESXi 4.0 Host, the script does not complete for me. :

C:\Program Files\VMware\VMware vSphere CLI\bin>vmwarevSphereHealthCheck.pl --ser
ver hq200-esx02 --username root --type host
Enter password:
Generating VMware vSphere Health Report 1.2 "vmware_health_report.html" ...

This can take a few minutes depending on environment size.
Get a cup of coffee/tea and check out http://www.engineering.ucsb.edu/~duonglt/v
mware/
Can't locate object method "commmunity" via package "HostSnmpDestination" at C:\
Program Files\VMware\VMware vSphere CLI\bin\vmwarevSphereHealthCheck.pl line 180
6, <STDIN> line 1.

End Disconnect

My workaround was to use vicfg-snmp.pl with "--disable" to disable SNMP, run the script again and then I get a Report, then use "--enable" to enable SNMP again.

I am not familiar with sciptin with Perl, so when I look at line 1806 of the script I don't see what to change. . Any suggestions?

The script's data collection and reporting capabilities are fantastic.

Thank you for developing and sharing it!

The issue ended up being a typo in one of the variables, I had an extra m in community which is why you saw the error message with not being able to locate the object. I did not have enough time to test SNMP section in VI3 version of the script: VMware Health Check Report v0.9.4 which was noted in the document and carried over to the vSphere version.

I've fixed the issue and actually re-did the output for the SNMP section and hopefully it'll be neater.

Thanks for the comments and try version 1.3 which has been uploaded and let me know if it resolves the issue.
