check_ilo2_health

Fix for `Can't call method "new" on an undefined value at ./check_ilo2_health.pl line 221` on XI. Replace `Nagios::Plugin` with `Nagios::Monitoring::Plugin`in PERL modules to install and replace all references of `Nagios::Plugin` in `check_ilo2_health.pl` with `Nagios::Monitoring::Plugin`

Unfortunately Smart Array equiped servers are not available now in 2022. We had to use that one with LSI RAID controller, but apparently we have problem monitoring hdd status now(?)

Below is tail of output with -c -v parameters.

Running on CentOS 8 with Perl v5.26.3 I get this error:
Can't call method "new" on an undefined value at ./check_ilo2_health.pl line 221

Is this an issue with Perl version not supported by the script ?

To resolve the HTTP/1.1 501 Not Implemented error, be sure to use the -3 option on the check command.

Hello

This is a great plugin but is there a reason why it isnt on GitHub? Would make it easier to contribute code....

Is there anyway to ignore if only some of the fans have issues. As in not go critical, stay ok until 4 out of 6 fans are in error?

It works for me with ubuntu 20.04 Server

For all who stuck in dependency hell, I get it running with this:

apt install libssl-dev
apt install zlib1g-dev
apt install expat
apt install libxml-sax-expat-incremental-perl

Hi,

i am using version 1.64. What´s wrong if i get the following with check_ilo2_health164.pl -H [hostnanme ilo interface] -u [username] -p [password] -v:
-----
hostname is [hostname]
retry: 0
HTTP/1.1 501 Not Implemented

Hi. Help me please.

I check ILO2 using this command:
./check_ilo2_health.pl -H -u -p -c

Script returns this error message:
Can't use string ("Smart Error") as a HASH ref while "strict refs" in use at ./check_ilo2_health.pl line 788.

Then I have logined in server's ILO2 and saw one drive have "Smart Error" status.
Can you modify program that it processes this status correctly?

Hi!
We're using the Plugin in Version 1.63 and we got the following message on some ESX-Hosts:

Is there a possibility to Whitelist this Battery-Service?

Thanks for your reply and help.

I had my controller disable cache due to a battery failure, which I didn't care about cause my server doesn't store anything important.

Hello
I get check_ilo2_health with HP ILO 3 v. 1.88 not to run.

(./che..-u xx -p xx -H 172.30.10.202 -3)
ILO2_HEALTH2 UNKNOWN - ERROR: Failed to establish SSL connection with 172.30.10.202:443 SSL connect attempt failed error:14094410:SSL routines:ssl3_read_bytes:sslv3 alert handshake failure.

For those with problems with ILO3, you have to specify the SSL cipher. In my case, in order to connect with an ILO 3 v1.89, I had to use:
--sslopts 'SSL_cipher_list => "DES-CBC3-SHA",SSL_verify_mode => SSL_VERIFY_NONE'

You can check available ciphers of ILO using cnark (http://blog.techstacks.com/cryptonark.html):
cnark.pl -h 192.168.2.66 -p 443 --insecure

Trying to make it work but I get the error:

ILO2_HEALTH UNKNOWN - ERROR: Failed to establish SSL connection with XX.XX.XX.XX:443 SSL connect attempt failed because of handshake problems error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure.

Trying to run it from ubuntu 14.04 server using 1.60 version of script, against a ProLiant DL380 G7 server with iLO3 1.87..
Tried all the hints in the comments...
Any help would be appreciated

REally good plugin that has been working really well for us on all version of iLO ... except one DL380 which is running iLO4

I get the exact same error that is alos reported in January 2016 further don this thread:-

CHECK_ILO2_HEALTH.PL UNKNOWN - plugin timed out (timeout 15s)

Tried various options on the command line but as yet I've been unable to get this to work.

Thank you for the plugin.
It works with different options with most of my servers but one where I get the following:
ILO UNKNOWN - ERROR: Failed to establish SSL connection with 192.168.1.63:443 IO::Socket::IP configuration failed.

Any help is much appreciated.
Thanks
P.S. plugin version 1.60

If you get an error like this:
ILO2_HEALTH UNKNOWN - ERROR: Failed to establish SSL connection with :443 IO::Socket::IP configuration failed.
you have to change the tls value in the source code.
ILO3: change TLSv1 to TLSv11
ILO4: change TLSv1 to TLSv12
Tested with ILO3 v1.87+ and ILO4 v2.4+

This works well, after I patched it to use Monitoring::Plugin instead of Nagios::Plugin (that has now been removed because of a Nagios Enterprise dispute).

For v1.60 replace line 164 with
use Monitoring::Plugin;
and line 177 with
our $p = Monitoring::Plugin->new(

cool plugin, started with a minor "Nagios::Plugin" issue, replaced it with Monitoring::Plugin or Nagios::Monitoring::Plugin

and now it's working when run ./check_ilo2_health.pl -H -u -p

But because I have seperated IP (xxx.xx.xx.xxx), one for server interface and one for ilo interface (xxx.xx.yy.xxx) the check_ilo2_health.pl try to connect the server IP, do I really need to hardcode the ILO IP in the service definition or any surgestion for multiple IP

ex.

define host{
use ...
host_name ...
address xxx.xx.xx.xxx
_ILOADDRESS xxx.xx.yy.xxx
}

How would the service definition look for this?

It's a very good tool, working very well with ilo 2/3/4, but when I try to use with newest ilo4 version it's not working and i got the message:

CHECK_ILO2_HEALTH.PL UNKNOWN - plugin timed out (timeout 15s)

but for all ILO 2/3 and 4 firm version below 7 it's working properly. COuld you please help me to solve it?

./check_ilo2_health.pl -u username -p password -n -H 10.0.1.2 -t 60 -g

This failing with the error:
ILO2_HEALTH UNKNOWN - ERROR: Syntax error: Line #0: syntax error near "" in the line: "".

But withour -g i get:
ILO2_HEALTH OK - (Board-Version: ILO2)

Throws
ERROR: Failed to establish SSL connection
just as the ones below.
This is on FreeBSD 10-STABLE with OpenSSL 1.0.1p and IO-Socket-SSL-2.016. Setup worked OK on previous versions and so far have not figured out how to patch - not very good at Perl...
Works great on a lot of other combos of DL360/380 G5/6/7/8!

there is a problem with Debian 8 or rather openssl 1.x
to fix the problem you have to replace following:

new(PeerAddr => $host, SSL_verify_mode => SSL_VERIFY_NONE, $sslv3 ?
'SSLv3' ) : () );
---
> $client = new IO::Socket::SSL->new(PeerAddr => $host, SSL_verify_mode => SSL_VERIFY_NONE, SSL_version => $sslv3 ?
> 'SSLv3' : 'TLSv1' );

Hi,
i get the following error: ILO2_HEALTH CRITICAL - Drive Bay 1: Spun Down, Drive Bay 2: Spun Down, Drive Bay 3: Spun Down, Drive Bay 4: Spun Down, Drive Bay 5: Spun Down, Drive Bay 6: Spun Down, Drive Bay 7: Spun Down, Drive Bay 8: Spun Down

With this command:$USER1$/check_ilo2_health.pl -H $ARG3$ -u $ARG1$ -p $ARG2$ -c -o -d -n -t 60

Is this an unsupported Server for "-c: check drive bays"? ProLiant DL380 G6

First of all, thanks for this plugin! :)

I'm getting this error:
./check_ilo2_health.pl -H [iLO] -u [USER] -p [PASSWORD]
Bareword "SSL_VERIFY_NONE" not allowed while "strict subs" in use at ./check_ilo2_health.pl line 384.

How can i solve this?

Hello from Germany. We use this plugin for some years now and it is great. Current Version 1.56 is installed on our nagios system.

But at the moment we ran in a little problem since we installed the latest ILO 4 2.03 firmware HP submitted in january 2015. - Now nagios/the plugin shows a "Power_Supply Inlet Temperature Warning" on some ILO4 servers although the ILO4 itself is happy with all temperatures.

ILO2_HEALTH WARNING - (Board-Version: ILO=3) Power_Supply_2: Inlet Temperature Warning

Any ideas on that ?

It does what it says. Thanks

./check_ilo2_health.pl -H x.x.x.x -u user -p password

and i get:

ILO2_HEALTH UNKNOWN - ERROR: No parseable output.

needed to add SSL_version => 'TLSv1' to connect command to make it work after ubuntu upgrade.
if i did not do that, i got SSL error

$client = new IO::Socket::SSL->new(PeerAddr => $host, SSL_verify_mode => SSL_VERIFY_NONE, SSL_version => 'TLSv1') or die "error=$!, ssl_error=$SSL_ERROR";

Seems like the link posted for the updated version of this plugin is dead. Is there an alternative location to download from?

Good plugin, we had problems with it working on ILO4 for two reasons, one the ILO can take a while to return the results, fix this by specifying -t 120 (but make sure your timeout for nagios is long enough in the nagios.cfg).

The second issue is that the ILO4 often returns N/A in its temperatures, you can fix this as, by not trying to set the perdata if the value contains N/A follows:
Line 439:
if ( defined($cautiontemp) && defined($criticaltemp) && ($cautiontemp !~ m"^n/a$"i)) {
if ($criticaltemp =~ m"^n/a$"i) {
$p->set_thresholds(
warning => $cautiontemp,
);

} else {
$p->set_thresholds(
warning => $cautiontemp,
critical => $criticaltemp,
);
}

Hi,
I am trying this script (version 1.58) with an iLO4 (sw=1.30) DL360p Gen8.

I only get temperature values in return.

If I add the -n option it looks like:

./check_ilo2_health.pl -u USER -p PWD -3 -n -H 10.10.10.10 -t 60
ILO4_HEALTH OK - (Board-Version: ILO>=3)

Running it in verbose mode (-v) it looks like it can get info about fans, cpu etc.

But it is not displayed. Can this line in the verbose output be a hint what is missing?

Scripting utility should be updated to the latest version.

HAve anyone else had the same problem? Any idea what might be wrong?

Very excellent.

For me, with ilo2 and latest firmware, i have aa error :
ILO2_HEALTH UNKNOWN - ERROR: Failed to establish SSL connection with *****

Changed :
$client = new IO::Socket::SSL->new(PeerAddr => $host);

to:
$client = new IO::Socket::SSL->new(PeerAddr => $host,SSL_verify_mode => SSL_VERIFY_NONE);


After, check is fully ok.

I would love to make this work on our iLO4 servers, has anyone been able to get it working?

I downloaded the latest version via the review by: "Link to Version 1.55 / ILO4
bypeetsche, March 8, 2013" but when I run the command I only end up with [CHECK_ILO2_HEALTH UNKNOWN - plugin timed out (timeout 15s)]. I followed the instructions to install it and already had the 3 modules installed and can reach the management interface via https. I get the same output whether I try it on the commandline as root or via Nagios interface as nagios user.

Any response would be helpful.

Works for me for years!

Here you can find the newest version:

https://www.monitoringexchange.org/attachment/download/Check-Plugins/Hardware/Server-%2528Manufacturer%2529/HP-%2528Compaq%2529/check_ilo2_health/12-08-5_08-33-56_check_ilo2_health.pl

This plugin is great. The source plugin is well documented, installation dependencies well documented, works out of the box in nagios. I am fairly new to nagios and was able to figure this out.

I could get nitpicky and ask for more features but 5/5 since it does exactly what it says it does.

Some notes. The nagios box we are using is *nix based and I was able to find all the dependencies via yum.
yum install perl-IO-Socket-SSL.noarch
yum install perl-XML-Simple.noarch
yum install perl-Nagios-Plugin.noarch

The only small hiccups I had were in configuring nagios. I needed to setup the host.cfg hostaddress as the hostname as opposed to the IP address for some reason. Also, our particular iLO2 password has odd characters that confuse the shell so I needed to add quotation marks around the password in the nagios config.

Just some tips that were difficult for me to figure out since I am new to this. Plugin is great.

Works great with iLO3 but cannot make it work on iLO4 - Assistance appreciated

Keep up the good work. Working very well with ILO3 (with -3 parameter).

I really like this script, but this listing needs to be updated to the latest version. I'm currently using 1.52 from the page:

https://www.monitoringexchange.org/inventory/Check-Plugins/Hardware/Server-%2528Manufacturer%2529/HP-%2528Compaq%2529/check_ilo2_health

Which is now working properly on my iLO2. It would be nice to see all the switch options as well, such as -o for checking power, -a for checking fans and -c for checking drives.

Works great with HP's ILO version 2. Anyone know how to make it work with ILO version 3 firmware?

This plugin is great.
Anyway I have question after read the code. There is commented warning "do not override previous return value from overall health", what's the effect if I try to override the value? I want to override ambient temperature warning and critical values to lower value, since one day I found that the air conditioner in my server room didn't work and the temperature hit about 30 C (some reference said ideally it should be about 20). Is it OK to ask question here?
thanks In advance

Works great..

i had a little trouble getting all the packages to work that this script needs, but finally got them all and now it runs perfect :)

Tho i have some idears that would make this plugin alot better:

1. to support iLO1 (we have a couple of old servere, with iLO-1 cards.)

2. if you have a server with a lot of temperature sensors, the output list from this plugin is HUGE and confusing (i have a server with 25 temperature sensors!) and this plugin just outputs them all as "temp_" would be great with the names description/name there too.

3. we use the "service description" in nagios a lot, and the description from this plugin is confusing and shows a lot more info than needed.
a great feature would be to have the plugin monitor only 1 thing, for example the temperatures only. or the HDD's only. that way i would create a server check for each to make out nagios installation clean and easy to understand.

4. maybe an option to choose a specific temperature sensors to check? (e.g "temp_15")

5. a option to only veiw the RAID/disk status.

i think all the above is possible the way this plugin is already checking the health of the server, since all that output is in the XML, but some of it gets ignored.
But that was just my thoughts on what could make this plugin better :)

else this is an awesome plugin, and thanks alot for sharing it!!

Good plugin! Had to patch it to make it work with iLO2 on HL DL360 G6 (iLO2 drive status issue)

Really nice! Also works with ilo3!
For me I had to define /usr/lib/perl before the command line in the commands.cfg

What is the reason that he return Null??

Hi,

just tested this plugin against HP BladeCenter iLO, and it works very well. Running nagios 3.0.x on Debian 5.0.x. Had to install some of the perl modules using cpan, but the rest were avaiable in Debian's apt tree.

I used this plugin to check the status on a farm of HP Servers. It worked very well. Too bad the old iLO vers 1 doesnt provide the hardware info. I installed it on a Debian Lenny Nagios Server using the info provided by the author. My special Thanks to the author of this script.
