reuse of nagios scripts and catch exit code about nri-flex

[haihongren]

are you able to share the output of the script? what format is it? thanks!

[sdeedee]

Just a sample (all nagios checks works the same way)
root@monworker001:/var/db/newrelic-infra/custom-integrations# /usr/lib64/cmbmonit/plugins/check_load -w 0,3,2 -c 1,6,4
WARNING - load average: 0.01, 0.07, 0.08|load1=0.010;0.000;1.000;0; load5=0.070;3.000;6.000;0; load15=0.080;2.000;4.000;0;

So I want to catch output into a variable. It can be 1 line but also multiple lines (in case of warning/critical).

Thanks.

I am not sure what metrics you are trying to get from the output.
With the following sdeedee.yml config:

name: sdeedee
apis:
  - name: sdeedee
    commands:
      - run: cat sdeedee.abc
        split: horizontal
        row_header: 0
        set_header:
          [
            status,
            loadAverage1,
            loadAverage2,
            loadAverage1,
            load11,
            load12,
            load13,
            load14,
            load51,
            load52,
            load53,
            load54,
            load151,
            load152,
            load153,
            load154,
          ]
        regex_match: true
        split_by: '(\S+).*?(load average:)\s+(.*?),\s+(.*?),\s+(.*?)\|load1=(.*?);(.*?);(.*?);(.*?);\s+load5=(.*?);(.*?);(.*?);(.*?);\s+load15=(.*?);(.*?);(.*?);(.*?);'

I got the following result:

				{
					"event_type": "sdeedeeSample",
					"integration_name": "com.newrelic.nri-flex",
					"integration_version": "0.8.3-pre-3-gf5a6601-dirty",
					"load11": 0.08,
					"load12": 0.01,
					"load13": 5,
					"load14": 6,
					"load151": 0,
					"load152": 0.08,
					"load153": 2,
					"load154": 4,
					"load51": 0,
					"load52": 0.07,
					"load53": 3,
					"load54": 6,
					"loadAverage1": 0.07,
					"loadAverage2": 0.01,
					"status": "OK"
				}

Please insert a blank line before the first line in the current output for multiple line output as Flex expects the metrics starts from the 2nd line onwards currently (for multi line output).
For single line output, it should work fine.

So this above yml config should work for the OK output.

OK - load average: 0.01, 0.07, 0.08|load1=0.010;5.000;6.000;0; load5=0.070;3.000;6.000;0; load15=0.080;2.000;4.000;0;

Please let me know how you go with the yml config.

./nri-flex -config_file sdeedee.yml -pretty -verbose

[haihongren]

In the above yml file, i am using "run: cat sdeedee.abc" to simulate your script output.
the "sdeedee.abc" has the following content:
OK - load average: 0.01, 0.07, 0.08|load1=0.010;5.000;6.000;0; load5=0.070;3.000;6.000;0; load15=0.080;2.000;4.000;0;

Hi @haihongren, thanks! I can go on with your example. The multi line output I can cover by removing newline characters so the output is always a single line.

Just two other questions related to variables.

Is it possible to use variables in de flexConfig file?

/usr/lib64/cmbmonit/plugins/check_load -w @VARIABLES_ARG_WARNING -c @VARIABLES_ARG_CRITICAL
@VARIABLES_ARG defined somewhere in the flexconfig file:

• variables:
  arg.warning: 3,4,5
  arg.critical: 6,7,8

Is it possible to reuse the run command and exit status of the command as variable to pass as attribute? Like in bash $? returns exit code of the command and $0 the command. To have:
custom_attributes: command.exitcode: $? command.run: $0

[haihongren]

Please look at the following example:

• variable_store
• custom_attributes
• ${var:myfile}

name: sdeedee
variable_store:
  myfile: sdeedee.abc
  myCommand: cat
apis:
  - name: sdeedee
    commands:
      - run: ${var:myCommand} ${var:myfile}
        split: horizontal
        set_header:
          [
            status,
            loadAverage1,
            loadAverage2,
            loadAverage1,
            load11,
            load12,
            load13,
            load14,
            load51,
            load52,
            load53,
            load54,
            load151,
            load152,
            load153,
            load154,
          ]
        regex_match: true
        # split_by: '(\S+).*?(load average:)\s+(.*?),\s+(.*?),\s+(.*?)\|load1=(.*?);(.*?);(.*?);(.*?);\s+load5=(.*?);(.*?);(.*?);(.*?);\s+load15=(.*?);(.*?);(.*?);(.*?);'
        split_by: '(\S+).*?(load average:)\s+(.*?),\s+(.*?),\s+(.*?)\|load1=(.*?);(.*?);(.*?);(.*?);\s+load5=(.*?);(.*?);(.*?);(.*?);\s+load15=(.*?);(.*?);(.*?);(.*?);'
        custom_attributes:
          myCommand: ${var:myCommand}
          myFile: ${var:myfile}

I would also recommend you to look the following wiki document:

https://github.com/newrelic/nri-flex/wiki/Functions#store_variables
https://github.com/newrelic/nri-flex/wiki/Functions#lookup_file
https://github.com/newrelic/nri-flex/wiki/Functions#store_lookups

• It does not capture exit code for Command at this moment, you can raise a feature request.
• It does capture http return code if you are using url. For example:

name: nginxFlex
apis:
  - name: nginxStub
    url: http://127.0.0.1/nginx_status

Thanks, that was what I needed.

I am closing out this issue for now. Thanks!
