check_sap_health.. and then go crazy

[Support_Talea]

Hi,

Have any of you ever managed to install the plugin in question?

https://labs.consol.de/nagios/check_sap ... index.html

It sounds crazy, I can't find the right solution to get it started.

could not load perl module SAPNW

Hi,
I looked inside "check_sap_health" and the error came from

Code: Select all

if (eval "require sapnwrfc") {

  } else {
    $self->add_message(CRITICAL,
        'could not load perl module SAPNW');
  }

Looks like you need to install "sapnwrfc" perl module.

Code: Select all

$ perl -MCPAN -e "install sapnwrfc"

My "sapnwrfc" install failed, so I have to force it:

Code: Select all

cpan -f -i sapnwrfc

Setting this up was not easy. I have spent quite a bit of times on this which I should not since we do not support scripts from Nagios Exchange.

I do not have an SAP account to be able to download NW SDK, so i picked up the old "nwrfcsdk.zip" on the web so that I can copy those SDK libraries based on the instruction.

Since I don't' have SAP, I'm not able to test the script, but I was able to bring up the help:
[root@vt-nagiosxi-61 libexec]# ./check_sap_health --help

Code: Select all

 --regexp
   Parameter name/name2/name3 will be interpreted as (perl) regular expression
 --warning
   The warning threshold
 --critical
   The critical threshold
 --warningx
   The extended warning thresholds
   e.g. --warningx db_msdb_free_pct=6: to override the threshold for a
   specific item
 --criticalx
   The extended critical thresholds
 --units
   One of %, B, KB, MB, GB, Bit, KBi, MBi, GBi. (used for e.g. mode interface-usage)

   It works only for specific checks. Which ones? Try it out or look in the code.
   --mitigation warning ranks an error as warning which by default would be critical.
 --lookback
   The amount of time you want to look back when calculating average rates.
   Use it for mode interface-errors or interface-usage. Without --lookback
   the time between two runs of check_nwc_health is the base for calculations.
   If you want your checkresult to be based for example on the past hour,
   use --lookback 3600.
 --environment

 --negate
   Emulate the negate plugin. --negate warning=critical --negate unknown=critical
 --morphmessage
   Modify the final output message

   It's a perl regexp and a substitution.
   Example: --morphperfdata '(.*)ISATAP(.*)'='$1patasi$2'
 --selectedperfdata
   The parameter allows you to limit the list of performance data. It's a perl regexp.
   Only matching perfdata show up in the output
 --report
   Can be used to shorten the output
 --multiline

 --with-mymodules-dyn-dir
   Add-on modules for the my-modes will be searched in this directory
