Litmus Edge Manager FAQs
- You can get started with Litmus Edge Manager: Getting Started
- Read about Litmus Edge Manager here: Litmus Edge Manager User UI
No, Litmus Edge Manager is based on the model purchased from Litmus. Litmus Edge Manager is the management suite for Litmus Edge.
These attributes are sent by the devices. If it does not display:
- Check the device status from the Edge Devices pane to see if data is connected. See Step 7: Verify Edge device activation in Litmus Edge Manager.
- Check the device information in the edge device. See Information.
- Try double checking your connection parameters.
- If the parameters are correct, check your firewall settings.
Data sent to Litmus Edge Manager must be in a special format, as shown in the JSON schema in the Project settings page. If Litmus Edge Manager cannot parse incoming messages, the messages only appear in the Raw tab.
This may be happening because your VM is configured with DHCP and received a new IP address after the reboot.
For LEM version earlier than 2.31.0:
Log in to the Admin Console and change the base domain name to the new IP address.
For LEM version 2.31.0 and later:
- SSH to the VM and obtain root access.
- Edit /etc/default/lem-common.
- Change LEM_BASE_DOMAIN_NAME to lem.local.
- Wait 5 minutes for the system to reconfigure the domain names and then log in again.
Litmus Edge Manager supports MQTT protocol to remotely manage a device:
MQTT
Litmus Edge Manager supports 3 types of MQTT topics:
- request - to send manage requests to a device
- response - to receive responses from a device
- data - to receive data from a device
Request/response formats are not defined.
For example: If you can program your device to reboot when it receives {"command": "reboot"} from the request topic, you can reboot your device remotely.
If you open the MQTT tab on the Device Details form, you can see Request/Response tabs to manage MQTT devices online.
To accomplish management tasks, you must program your device.
The Batch Device Management feature offers operations similar to those described above, but you can define batch commands (MQTT) and schedule these commands to execute against a group of devices.
You can remove a project from the Project List or from the Remove Project section in the Project Settings > Settings tab.
Use Litmus Edge. All data that appears in the Explore tab is available in Litmus Edge as well.
- We do security testing with every release.
- We prevent security issues through REST and MQTT protocols. They only use secure transports, such as TLS and DTLS. We do not support unencrypted transports between the two products.
- All security credentials established during cloud activation are securely stores on the Litmus Edge device and they are not exposed to the end user. It is impossible to alter these credentials after activation as long as physical security of the Litmus Edge gateway is maintained.
- Alert - The Litmus Edge Manager Alerts feature allows a user to define notifications based on rules. Rules comprise a set of conditions that define an abnormal state of a device. For example: No data received from a device in more than two minutes, or the temperature went below 30 degrees. First, define Actions. Actions are the types of notifications, such as Slack or Webhook. Then, create a Trigger. A trigger is a combination of device tags, a set of rules, and an action. Once triggered, Litmus Edge Manager sends the alert notification to the defined destination. Alert notifications can be viewed on the Litmus Edge Manager dashboard as well as from email and third-party web applications, such as Slack. The Incidents tab on the projects page lists the alerts that were generated.
- Event - Events list the Litmus Edge Manager configuration activities that occurred for a project within a company. For example: Added a new project, or deployed a new device.
- Incident - If a device reaches an abnormal state according to the rules, then Litmus Edge Manager will create a new incident and send notifications. The Incidents tab lists the alerts that were generated. When a device returns to a normal state, the open incident will be closed and Litmus Edge Manager will send another notification with an incident resolved message.

We strongly recommend ESXi version 6.7 or higher.
Find out the following:
- The version of the Litmus Edge and the Litmus Edge Manager.
- The version of a component if it is not working.
- The type of license installed.
- If the network is properly configured.
- If the NTP/DNS settings are correct.
- If you are using the correct PLC driver and IP address.
Alert history is not deleted. It is kept as long as there is space in the database.
After the alert history database becomes full, the system stops accepting data. In upcoming releases, we will develop a more sophisticated data life cycle management.
Not at this time. In upcoming releases, Litmus Edge Manager will be able to deploy LDAP/AD settings for various Litmus Edge devices.
Currently, a template consists of: PLC configurations (device settings and tags) and Flows.
You can select a mix of both types and create as many templates as you want.
These templates can then be uploaded from the Litmus Edge Manager Admin Console so that they are available to all the companies, or from the Litmus Edge Manager at a Company level so that they are available to all the Projects.
You can create different groups of Litmus Edge devices and select which template you want to deploy to a selected group of devices.
In upcoming releases, we will include CC as well as a few other configurations.
- Litmus Edge Manager supports the MySQL protocol for ClickHouse. If the BI tool supports MySQL, it can connect to ClickHouse. Some smart BI tools may use MySQL system tables that are not present in ClickHouse, so they should be tested.
- Litmus Edge Manager allows you to connect to the ClickHouse underlying database. See https://clickhouse.tech/docs/en/interfaces/third-party/integrations/ to find the native connectors that ClickHouse uses.
When an activation fails, there will be an Activation Stage Message that reports the exact cause(s). Here are some potential fixes:
- Ensure port 443 is opened.
- Ensure 51820/UDP is open for the Litmus Edge instance.
- Ensure the Remote Access protocol is not blocked at all.
- Ensure the time synchronizations setting between the Litmus Edge Manager and Litmus Edge is working properly.
- For Docker-run Litmus Edge instances, check for NETADM capability.
- For <3.2.0 Litmus Edge instances, ensure Remote Access modules on each host system (where the LE is installed) are operating properly.
The backup process for LEM consists of a compressed file downloaded from the LEM Admin UI. The data is updated every 24 hours and is maintained on the server for seven days. See https://docs.litmus.io/edgemanager/admin-console-backup for details on how to backup LEM.
LE backup files have a .dat file extension, while LEM backup files do not have any file extension. Both types of files are used to restore devices to their last backed-up state, but LE backups can only be restored through the LE user interface, while LEM backups must be restored through the LEM platform and cannot be uploaded directly to the LE UI.
