Introduction

Agent-based custom monitors are user-defined instrumentation for specialized workloads. OspRamp provides native monitors, however, you can also create custom monitor by writing your own scripts.

Using custom monitor, you can define remote metrics and metric conditions for a monitor and gather the performance insights using an agent that runs on Windows and Linux devices. OpsRamp generates an alert when the threshold surpasses the conditions defined in a metric.

Along with Agent-based monitoring, OpsRamp also provides support for Agentless Custom Monitors.

Creating agent-based custom monitors

The agent-based Custom monitor helps you to create your own script to create new monitors. To write a script, you must choose a scripting language supported by OpsRamp. For example, Python, Windows PowerShell, and SHELL.

To create agent-based custom monitors:

  1. Go to Setup > Monitoring > Agent Custom Monitors.

  2. From AGENT CUSTOM MONITORS, click + Add.
    CREATE MONITOR SCRIPT screen appears.

  3. From CREATE MONITOR SCRIPT, provide details for the following parameters, and Save:

    • Select Script Type: Refers to the scripts applicable for Partners and Clients. 
    • Script Name: Refers to the unique name provided for the script.
    • Description: Refers to the detailed description that explains the purpose of the script.
    • Execution Type: Refers to the type of execution. Select as desired. Depending on the selected type of execution, the screen displays additional fields. For example, if you select EXE as execution type, then the File field appears below. You can use the Choose File to upload the required .exe file. If you select any other execution type, you need to provide Command/File Name and the corresponding script extension.
    • Metrics: Refers to the Metrics required for the script. To add Metrics:
      1. From Metrics, click + Add Metric. Metric fields appear.
      2. Provide the metrics details.

    AGENT CUSTOM MONITORS screen displays the new monitor.
