custom plugin "Error in running plugin timeout"

[raffaelespazzoli]

Hello, I have a custom plugin define as follows:

ontap-san-test.json: |
    {
      "plugin": "custom",
      "pluginConfig": {
        "invoke_interval": "30s",
        "timeout": "5s",
        "max_output_length": 80,
        "concurrency": 3,
        "enable_message_change_based_condition_update": true
      },
      "source": "ontap-san-custom-plugin-monitor",
      "metricsReporting": true,
      "conditions": [
        {
          "type": "OntapSANProblem",
          "reason": "OntapSANIsUp",
          "message": "Ontap-san connection service is up"
        }
      ],
      "rules": [
        {
          "type": "permanent",
          "condition": "OntapSANProblem",
          "reason": "OntapSANIsDown",
          "path": "./custom-config/ontap-check.sh",
          "timeout": "3s"
        }
      ]
    }
  ontap-check.sh: |
    #!/bin/bash

    # This plugin checks if the ntp service is running under systemd.
    # NOTE: This is only an example for systemd services.

    readonly OK=0
    readonly NONOK=1
    readonly UNKNOWN=2

    # Return success if we can read data from the block device
    if timeout -k 2s 1s dd iflag=direct if=/dev/ontap-san-test bs=4096 count=1 of=/dev/null; then
      echo "ontap-san-test is accessible"
      exit $OK
    else
      echo "ontap-san-test is NOT accessible"
      exit $NONOK
    fi

When I artificially generate the error condition, the node-problem-detector prints out the following:

Error in running plugin timeout "./custom-config/ontap-check.sh"

I took a look at the code, and this log log line does not seem to be in the right place (

node-problem-detector/pkg/custompluginmonitor/plugin/plugin.go

Line 186 in 6cffddb

klog.Errorf("Error in running plugin timeout %q", rule.Path)

).
But after that log it's unclera to me why nothng else happens.

Any help would be appreciated.
