REST API Basic Filters

Product Documentation

When making API calls using LogicMonitor REST API, you may get too many results. To make your search more specific, you can use API filters. You can use the pattern <field name><operator><values> to create filters.

In this support article we have used REST API /alert/alerts and /device/devices as examples to explain how filters can be used. You can filter endpoints with the values supported by the following operators:

Operator	Description
:	Equal
!:	Not equal
>	Greater than
<	Less than
>:	Greater than or equal
<:	Less than or equal
~	Contain
!~	Does not contain

Users with administrator role will receive more results than users with non-admin roles. Users with administrator role have more privileges and access to most of the devices. Whereas, users with non-admin roles get results based on the devices they have access to.

General Examples

In this section you can refer the following examples for any REST API endpoint.

Note: These are samples only and must be modified to suit your business requirements.

Filter resources whose color is red

filter=color:"red"

Filter resources whose name is *aaa and status is active

filter=name:"*aaa",status:"active"

Filter resources whose status is active or suspend

filter=status:"active"|"suspend"

Filter resources whose contact object’s name is hoo

filter=contact.name:"hoo"

Filter resources whose property array has at least one element with name as location

filter=properties.name:"location"

Filter resources whose status is suspend or name is aaa or bbb or ccc

filter=name:"aaa"|"bbb"|"ccc"||status:"suspend"

Search for all resources that contain keywords

filter=_all~"keyword"

Filters for `/alert/alerts` API Endpoints

You must consider the following points when using the filters:

When you filter an endpoint based on parameters, the result is consistent as long as there is no change (no new addition or deletion of alert) in the alert count even if you hit the API multiple times.
If you provide the Sort request attribute, then the result is sorted as per the alert property. For example, if the alert is sorted based on the startEpoch alert property, the result is sorted as per the startEpoch of the alert. If the startEpoch of some alerts is equal, then the result is sorted based on the ascending order of the alert ID property. Thus, the result is always consistent.
You can filter endpoints of GET alert list API (/alert/alerts). The response of the GET alert list API can be filtered using the request parameters (filters).
You can filter alert properties and their values only using the AND operator. For example, filter=<condition>,<condition>,… Where condition is <field name><operator><values>
You can filter /alert/alerts endpoints with multiple properties at a time. For example,
Request URL

{{url}}/alert/alerts?offset=0&size=300&sort=startEpoch&filter=startEpoch>:1653295431,startEpoch<:1658146793,severity:"4"|"3",cleared:"*",resourceTemplateName:"Host status",monitorObjectName~"pod-kube"

Here five filters are applied on alert properties: startEpoch, severity, cleared, resourceTemplateName, and monitorObjectName.

startEpoch is 1653295431 <= startEpoch <= 1658146793
severity can be either 3 or 4
cleared value can be true or false
resourceTemplateName equals to Host status
monitorObjectName contains pod-kube

In the response body this query lists the result as per the filters.

Examples: `/alert/alerts` filter

Filter alerts which are generated between the epoch range 1653295431 <= startEpoch <= 1663756550

{{url}}/alert/alerts?filter=startEpoch>:1653295431,startEpoch<:1663756550

Filter alerts with severity = 3 or 4. Severity 3 indicates error and severity 4 indicates critical alert.

{{url}}/alert/alerts?filter=severity:"4"|"3"

Display all alerts including cleared and uncleared alerts

{{url}}/alert/alerts?filter=cleared:"*"

Filter cleared alerts

{{url}}/alert/alerts?filter=cleared:true

Filter alerts with resourceTemplateName = Host status

{{url}}/alert/alerts?filter=resourceTemplateName:"Host status"

Filter alerts with monitorObjectName containing pod-kube

{{url}}/alert/alerts?filter=monitorObjectName~"pod-kube"

Filter alerts using 5 alert properties – startEpoch, severity, cleared, resourceTemplateName, and monitorObjectName. The result is sorted based on startEpoch (ascending order). Because the offset is 0 and the specified size is 300, out of all filtered alerts, the first 300 alerts are fetched.

{{url}}/alert/alerts?offset=0&size=300&sort=startEpoch&filter=startEpoch>:1653295431,startEpoch<:1658146793,severity:"4"|"3",cleared:"*",resourceTemplateName:"Host status",monitorObjectName~"pod-kube"

Filter alerts whose type is dataSourceAlert and are acknowledged

{{url}}/alert/alerts?filter=acked:true,type:"dataSourceAlert"

Filter alerts whose escalation chain is Secondary and alert rule name contains Critical

{{url}}/alert/alerts?filter=chain:"Secondary",rule~"Critical"

Filter alerts whose instanceName is HostStatus

{{url}}/alert/alerts?filter=instanceName:"HostStatus"

Filter alerts whose dataPointName is Latency

{{url}}/alert/alerts?filter=dataPointName:"Latency"

Filter alerts that are in SDT

{{url}}/alert/alerts?filter=sdted:true

Filter alerts which are cleared and have endEpoch <=1658820186

{{url}}/alert/alerts?filter=cleared:true,endEpoch<:1658820186

Filter alerts which are cleared and have endEpoch >1658820186

{{url}}/alert/alerts?filter=cleared:true,endEpoch>1658820186

Filter alerts which are cleared and have endEpoch <=1658820186 and endEpoch>=1658820079

{{url}}/alert/alerts?filter=cleared:true,endEpoch<:1658820186,endEpoch>:1658820079

Filters for /`device/devices` API Endpoints

You can use the following filters to refine API calls.

Filter device whose id is 44

{{url}}/device/devices?filter=id:44

Filter devices with name that ends with string service, and devicetype is 6

{{url}}/device/devices?filter=name:"*service",deviceType:6

Filter devices with hostGroupIds 24517 or 31

{{url}}/device/devices?filter=hostGroupIds:"24517" | "31"

Filter devices with inheritedProperties where one of the property names is snmp.community irrespective of the value of property.

{{url}}/device/devices?filter=inheritedProperties.name:"snmp.community"

Filter devices whose displayName contains string Member OR devices with id > 11. The result will display those devices which match one or both the filters.

{{url}}/device/devices?filter=displayName~"*Member" || id>11

Filter devices whose displayName contains string Member AND devices with id > 11. The result will display only those devices which match both the filters.

{{url}}/device/devices?filter=displayName~"*Member", id>11

Search for all devices that contain the keyword new device

{{url}}/device/devices?filter=_all~"new device"

Operator Examples

Contain and Does Not Contain (~ and !~) Operators

Run the following query:

{{url}}/device/devices?fields=autoProperties,name,id&filter=autoProperties.name:"predef.externalResourceID",autoProperties.value~"service"

In the response body this query lists IDs, names, and autoProperties of devices with autoProperties.name = predef.externalResourceID or any autoProperties.value with substring = service.

Note: It also lists autoProperty value containing only special characters or numbers.

{
"total":4865,
"items":[
{
"id":44,
"name":"Instance",
"autoProperties":[
{
"name":"predef.externalResourceID",
"value":"service_44"

Equal To, Contain, Greater Than, and Less Than (:, ~, >, <) Operators

Run the following query:

{{url}}/device/devices?filter=id<5000,displayName~"service",hostGroupIds:"1",createdOn>1559000000

In the response body this query lists all devices with ID less than 5000 AND displayName containing “service” string, hostGroupIds = “1”, and createdOn time > 1559000000
