The Remote Shell monitor enables using custom Bash, Perl, and Python scripts to monitor remote devices.


  • Remote System

    • Resource has SSH support.
    • Installation of one of the scripting languages, such as Bash, Python, and Perl.
    • All the libraries of the installed script are available in the remote system.
    • The custom script follows the predefined OpsRamp response format.
  • OpsRamp
    • Gateway version 5.5.0.
    • User credentials with permissions to create a metric, monitor, and template.
    • Access to the remote device requires a valid SSH credential.
    • Valid custom script execution path is provided in the monitors.


  • Do not support command arguments in the scripts.

Create metrics

You can create Custom Metrics using custom scripts.

  1. Select a client from the All Clients list.

  2. Go to Setup > Monitoring > Metrics.

  3. From the METRICS screen, click + Add and enter:

    • Collector Type: Select Application.

    • Application Type: Select Remote Shell.

    • Name: Enter a Name for the metric.

      • The recommended metric naming convention is <Prefix>_<Script Type>_<OS>_<Name> as naming convention for the metric. For example: rshell_bash_linux_disk_utilization, rshell.python.linux.cpu_utilization, and rshell_perl_linux_memory_utilization
    • Tag: User-defined tags for better filtering. For example, Application, Adapter, RemoteShell.

    • Display Name: Display Name provided for the metric.

    • Description: Reason for the metric.

    • Script: Enter the custom script in the Script text box. Refer to Bash script and JSON outputs example for single and multiple datapoints to view the example script.

    • Adaptor Type: Select Application.

    • Application Type: Select Remote Shell.

    • Name: Unique monitor name.

    • Description: Details of the added monitors.

    • Metrics: A metric is a measurement for a specific characteristic of the performance of a device.
      To add metrics:

      1. From Metrics, click Add Metrics. A maximum of 20 metrics is recommended. Adding more number of metrics in a monitor can cause performance issues.
      2. Search the metric and click Add Metrics. The metrics section displays the selected metric.
    • Configuration Parameters: A configuration parameter is a user input to help the metric collector. To add parameters:

      1. Enter Default Value for all the configuration parameters.

      2. Select the Configurable checkbox and click Add.

      3. Enter configuration parameters depending on your environment or devices. You can view the default value for the respective name selected. For example, the following shows the configuration parameters for a script type:

        • bash: rshell.bash.bin.path
        • python: rshell.python.bin.path
        • perl: rshell.perl.bin.path
        • custom executor: rshell.customexecutor.bin.path
  5. Click Save.

Secure Shell Create Monitor

Create templates

A template is an instance of a monitor and applied to devices.

  1. Select a client from the All Clients list.

  2. Go to Setup > Monitoring > Templates.

  3. From the TEMPLATES screen, click + Add.

  4. From MONITOR TEMPLATE, enter the following parameters:

    • Select Template Scope: Template type.

    • Collector Type: Select Gateway.

Monitor Template Graphs

Bash script examples

In these examples:

  • Datapoints are used for plotting graphs.
  • Tokens are used for alert information.
system_load=`cat /proc/loadavg | awk '{print $2}'`
printf "{\n\"datapoints\":{\n\t\"System Load\" : %s\n},\n\"tokens\": {\n\t\"Current System Load\" : \"%s\"\n}\n}\n" "${system_load}" "${system_load}"

Bash single datapoint and token

This example is a JSON output for a single datapoint and token.

    "System Load" : 1.60
"tokens": {
    "Current System Load" : "1.60"

Bash multiple datapoints and tokens

This example is a JSON output for multiple datapoints and tokens.

           "DiskC" : 50,
           "DiskD" : 81
   "tokens": {
           "" : "DiskC : 40 GB, DiskD : 100 GB",
           "disk_utilization.used" : "DiskC : 20 GB, DiskD : 50 GB"
