Juniper Mist Monitoring

Last updated on 03 November, 2022

LogicMonitor offers out-of-the-box monitoring for Juniper Mist organizations, sites, and devices. It is designed to monitor organization health, sites and traffic generated by the sites, Juniper Mist-managed devices (including Juniper Mist Access Points, EX-Series Switches, Session Smart Routers, and the status of these devices), and uses the Juniper Mist API to retrieve site device stats and data.


Adding Resources into Monitoring

You can add Juniper Mist resources by running a NetScan or you can add them manually. We recommend running a NetScan. NetScan creates devices under device groups for each Mist organization site, and adds an organization device. For more information, see What is NetScan.

You can automatically add devices using an Advanced NetScan; specifically, an Enhanced Script Netscan. For more information, see Enhanced Script Netscan. Ensure the following configurations are in place:

  1. Under Device Credentials > Use custom credentials for this scan, use the following properties: 
mist.api.keyMist API token
mist.api.orgMist Organization ID display name of your Mist Organization device and device group folder, defaults to Mist Organization
  1. When configuring the Enhanced Script Netscan, use Embed Groovy Script and use the following script:

Manual Setup

We recommend using the Enhanced Script Netscan, however, you can add Juniper Mist resources manually.

  1. Create a Juniper Mist Organization device group. For more information, see Adding Device Groups.
    • Property:
    • Value: Mist Organization ID
  2. Create a Juniper Mist Organization device. For more information, see Adding Devices.
    • Property: mist.api.key
    • Value: API key
  3. Add the devices to the Mist Organization device group under a Site device group with the following property added. For more information, refer to the Mist documentation for How do I find my Org and Site ID?
    • Property:
    • Value: Mist Site ID

Import the Juniper Mist LogicModules

Import all Juniper Mist LogicModules listed in the LogicModules in Package section of this support article. If these LogicModules are already present, ensure you have the most recent versions.  

Once the LogicModules are imported (assuming all previous setup requirements have been met), the addCategory_Juniper_Mist_Organization PropertySource must run to set the required properties to begin monitoring. Data collection will automatically begin for all devices after the Mist Organization device has started collecting data successfully in the Juniper_Mist_Org DataSource. For more information on importing modules, see LM Exchange.


  • This suite relies on Collector Script Caching to continuously retrieve and store data from the Juniper Mist API to minimize rate limiting constraints. Continuous data collection is maintained on the Mist Organization device through the Juniper_Mist_Org DataSource, which maintains a background thread that writes API responses to the collector script cache. addCategory_Juniper_Mist_Organization PropertySource must run first to set the proper category on this device. Juniper_Mist_Org DataSource must be running successfully for all other modules in this package to be successful.
  • During onboarding, you may wish to run Active Discovery manually on additional PropertySources in this package after Juniper_Mist_Org begins collecting data to expedite monitoring and topology mapping.
  • If data gaps are seen, verify Juniper_Mist_Org is functioning successfully and check script cache health in the LogicMonitor_Collector_ScriptCache DataSource.

Note: The API used to pull data has rate limits. Check Juniper_Mist_Org on your Mist Organization device in order to check if the API is unreachable or monitoring has hit the API rate limit.

When setting static datapoint thresholds on the various metrics tracked by this package’s DataSources, LogicMonitor follows the technology owner’s best practice KPI recommendations. If necessary, we encourage you to adjust these predefined thresholds to meet the unique needs of your environment. For more information on tuning datapoint thresholds, see Tuning Static Thresholds for Datapoints.
