Juniper Mist Monitoring

Last updated on 05 June, 2024

LogicMonitor offers monitoring for Juniper Mist organizations, sites, and devices. You can monitor organization health, sites and traffic generated by the sites, as well as Juniper Mist-managed devices such as Juniper Mist Access Points, EX-Series Switches, Session and Smart Routers. The Juniper Mist API is used to retrieve site device stats and data.


Adding Juniper Mist Resources

You can add Juniper Mist resources by using the following methods:

  • (Recommended) Advanced NetScan that creates devices under device groups for each Mist organization site. For more information, see What is NetScan.
  • Manually

Using Advanced NetScan to add Juniper Mist Resources (Recommended )

The recommended method for adding Juniper Mist-managed devices is to use an Enhanced Script Netscan with the LogicMonitor-provided Groovy script in this article. For a given Juniper Mist Organization, the Enhanced Script Netscan creates a group for the Mist Org and each Mist Site, and a resource for each Mist-managed device in the related group.

  1. Install the Juniper Mist LogicModules. For more information, see Juniper Mist LogicModules.
  2. In LogicMonitor, navigate to Resources > Add > Several Devices > Advanced NetScan.
    The Add Advanced NetScan page is displayed.
  3. Enter a Name that you want to associate with this NetScan. For example, Juniper Mist.
  4. Select the Collector that will execute the NetScan.
    By default, the NetScan assigns new resources to the collector executing the NetScan. You can override this behavior in Properties later and use multiple collector groups (for scale or logical connectivity). Select either an ungrouped collector or a collector group with failover.
  5. Select Enhanced Script NetScan from the Method drop-down list.
  6. From the Enhanced Script section, select Device Credentials > Use custom credentials for this scan.
  7. Add the following properties. Properties provide the NetScan with the required Juniper Mist API credentials and change how and where the NetScan creates and organizes resources.
mist.api.keyMist API tokenYes
mist.api.orgMist Organization IDYes Mist Org Name. This becomes the name of the root Resource Group for Juniper Mist, or becomes the name of top-level child Resource Group if you use the property to specify an alternate root folder.No name of the LogicMonitor Resource Group that this NetScan creates or uses if already existing. The value can be a nested child folder; for example, folder/folder/folder.No site names to include (others are excluded).No
By default, new resources created by the NetScan are assigned to the collector that runs the NetScan. This property uses a CSV file to override the default behavior and assign Mist devices to your desired collector(s) based on Mist Site and LM Collector names. The CSV file must be stored on the collector that executes the NetScan:

Linux: /usr/local/logicmonitor/agent/bin
Windows: C:\Program Files\LogicMonitor\Agent\bin

For more information, see Mapping Mist Sites to LM Envision Collectors.
mist.api.urlAlternate region URLs include:
A LogicMonitor API access id to search for duplicate resources in the NetScan prior to adding them to the portal. For more information on portal monitoring, see LogicMonitor Portal Monitoring.Yes
A LogicMonitor API key to search for duplicate resources in the NetScan prior to adding them to the portal. For more information on portal monitoring, see LogicMonitor Portal Monitoring.Yes
hostname.sourceAllows for selection of the source of the hostname that is used by the NetScan. This is useful in preventing duplicate device creation when conflicts are found for existing resources. For more information, see NetScan Troubleshooting.No
skip.device.dedupeAllows you to skip device deduplication checks, making LogicMonitor API credentials not required.No
  1. In the Filters section, enter the following. Filtering gives you control over which sites and device types that the NetScan creates.
PropertyDescription names of sites you want to include or exclude. By default (without this filter), the NetScan imports all sites as Resource Groups. Site names with spaces must include a backslash before the space.  For example: Site\ For\ APs, SiteD, Site\ 23
mist.device.typeComma-separated names of device types that the NetScan will include or exclude, depending on the operation setting.  By default (without this filter), the NetScan imports all device types. Valid device types are: apswitch, and gateway.
  1. When configuring the Enhanced Script Netscan, use Embed Groovy Script and use the following script:

Warning: Do not edit the script. Edited Enhanced Script NetScans are not supported. If the LogicMonitor-provided script is edited, LogicMonitor Support may (at their discretion) require you to overwrite your edits with the supported script if problems arise.

Juniper Mist Properties

Additional attributes and values for Juniper Mist.

Proxy Settings

The modules in this suite support HTTP connections using a proxy server. You can configure this in the Collector settings, see Configuring your Collector for use with HTTP Proxies, or with the following device host properties. Device host properties take precedence over Collector settings for proxy configurations.

proxy.enable(Optional) This suite is written to use collector proxy settings for HTTP calls configured by the user. To enable, add this device property with the value set to true. Set to false to override the use of configured collector proxy settings and connect without a proxy. Configure a proxy host to connect through that is different from collector configuration.
proxy.port(Optional) Configure a proxy port to connect through that is different from collector configuration.

Juniper Mist Troubleshooting

  • This suite relies on collector script cache to continuously retrieve and store data from the Juniper Mist API to minimize rate limiting constraints. For more information, see Collector Script Caching. Continuous data collection is maintained through the Juniper_Mist_API DataSource, which writes API responses to the collector script cache. Juniper_Mist_API DataSource must be running successfully for all other modules in this package to be successful.
  • During onboarding, you can run Active Discovery manually on additional PropertySources in this package after Juniper_Mist_API begins collecting data to expedite monitoring and topology mapping.
  • If data gaps exist, verify Juniper_Mist_API 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_API on your Mist Organization device in order to check if the API is unreachable or monitoring has hit the API rate limit.

LogicModules in Package

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.

Recommendation:As necessary, 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.
