Update Instance-level Thresholds
Last updated - 23 July, 2025
You can use LogicMonitor’s REST API to programmatically update instance level thresholds.
Note: As with all of our API calls, authentication is required.
/device/devices/{deviceId}/devicedatasources/{deviceDatasourceId}/instances/{instanceId}/alertsettings/{id} Where:
- {deviceId} is the id of the device you’d like to see thresholds for. You can get group Ids from a GET request to the devices resource.
- {deviceDatasourceId} is the id of the device datasource you’d like to see thresholds for. You can get this Id by making a GET request to the device datasources resource
- {instanceId} is the id of the instance you’d like to see thresholds for. You can get this id by making a GET request to the instances resource
- {id} is the id of the alert setting you’d like to update, from a Get instance-level thresholds request.
Request Parameters: You can include the following parameters in your PUT request:
Property | Required? | Description |
| alertExpr | No – defaults to no thresholds | The thresholds that should be associated with the datapoint. Note that you need to have a space between the operator and each threshold (e.g. > 1 2 3) |
| disableAlerting | No – defaults to false | Whether or not alerting will be disabled for the datapoint |
Example
The following Python script updates the threshold for the recvd packets datapoint for device datasource 3320 (which is Ping in api.logicmonitor.com):
#!/bin/env python import requests import json import hashlib import base64 import time import hmac #Account Info AccessId ='48v2wRzfK94y53sq5EuF' AccessKey ='H_D9i(f5~B^U36^K6i42=^nS~e75gy382Bf6{)P+' Company = 'api' #Request Info httpVerb ='PUT' resourcePath = '/device/devices/56/devicedatasources/3320/instances/1469/alertsettings/13363' queryParams ='' data = '{"alertExpr":"< 10"}' #Construct URL url = 'https://'+ Company +'.logicmonitor.com/santaba/rest' + resourcePath +queryParams #Get current time in milliseconds epoch = str(int(time.time() * 1000)) #Concatenate Request details requestVars = httpVerb + epoch + data + resourcePath #Construct signature hmac1 = hmac.new(AccessKey.encode(),msg=requestVars.encode(),digestmod=hashlib.sha256).hexdigest() signature = base64.b64encode(hmac1.encode()) #Construct headers auth = 'LMv1 ' + AccessId + ':' + signature.decode() + ':' + epoch headers = {'Content-Type':'application/json','Authorization':auth} #Make request response = requests.put(url, data=data, headers=headers) #Print status and body of response print('Response Status:',response.status_code) print('Response Body:',response.content)Python 3
