Maximum supported values with Finder (classic)
To guarantee the correct operation of Nexthink at an adequate level of performance, certain elements and aspects of a setup must be kept below their maximum values. This is because boundaries of varied nature appear in different contexts within the product.
Below is a comprehensive list of the maximum values within the platform:
The number of objects that an Engine instance can store
The alerts, services, metrics or actions that can be simultaneously enabled
The hierarchies and the levels that organize your groups of devices
The accounts, profiles and roles that grant access either to web interface or to Finder (classic), or both
The number of results to obtain from a query, and others.
Respect the limits presented in this document to avoid performance issues.

Lifetime of objects
The lifetime of an object in Nexthink is related to the configured data retention. In Portal, the metrics computed can extend their lifetime to several years and the details of count metrics last for as long as there is free disk space allocated for them. As for Engine, an object is kept in its database until all the events that are linked to that particular object have disappeared from the history of Engine.
There are three types of objects that are not immediately removed from Engine after losing all their linked events: devices, users and binaries. These objects have an associated maximum inactivity period that may go beyond the history of events in Engine. Thus, if the maximum inactivity period of an object has not elapsed, the object is not removed from the database, even when there is no event linked to the object left. When Engine records new activity for a device, a user or a binary, the inactivity period associated to the object is reset.
Because application and executable objects are linked to binaries, they are equally stored in the database of Engine for as long as a related binary exists. Therefore, the lifetime of applications and executables is determined by the maximum inactivity period of the binaries to which they are related.
Device

max_inactivity_period
User
Binary
2 592 000 s (30 days)
max_binary_inactivity_period
The max_inactivity_period and max_binary_inactivity_period settings are configurable. Contact Nexthink Support for more information.
Categories and keywords
There is no fixed maximum number of categories or keywords that can be applied to tag objects. However, a number of categories or keywords, especially keywords that specify auto-tagging conditions, may have an impact on the overall performance of a Nexthink setup. Thus, the maximum recommended values to keep your system under an acceptable level of performance are the following:
Category
25 per type of object
Keyword
800 per category (200 of which with auto-tagging conditions)
Auto-tagging condition
20 per keyword
Collector string tag
When identifying an installation of Collector by means of a string tag, the assigned tag has a maximum of 2048 characters.
Services
There is no fixed limit on the number of services that you can create in Finder. However, the maximum number of simultaneously enabled services is 100.
Alerts
Service-based alerts
Create a maximum of one alert per service. Therefore, a maximum of 100 service-based alerts are permitted.
Investigation-based alerts
There is no fixed limit on the number of alerts that you can create in Finder. However, the total number of enabled investigation-based alerts per Engine cannot exceed 150 alerts, including global and user-specific alerts. The distribution between global and user-specific alerts is as follows:
Global
50
My alerts + role based
10
Metrics
There is no fixed limit on the number of metrics that you can create in Finder. However, there is an actual limit on the number of simultaneously enabled metrics. During the night, Portal computes the values of enabled metrics only.
Metrics
3 000
Scores
There is no fixed limit on the number of scores that you can import into Finder. However, there is an actual limit on the number of simultaneously enabled scores. The maximum number of enabled scores is limited by two factors: storage and computation power required.
Storage
500 composite or leaf scores (including subscores in the count)
Computation power
200 scores of the Computation input type
The total maximum number of scores is therefore 500 scores, of which a maximum of 50 scores can be of the Computation input type. These are not absolute maximums and can be exceeded by contacting Nexthink Support.
The Digital Experience Score is embedded in the product. The scores that compose the Digital Experience Score are therefore regarded as part of the base product, such that they consume no part of the maximum number of scores available for the customer.
Engage and Act
The Engage and Act products store information on the user and device objects, respectively, by means of custom fields; that is, properties or attributes that are dynamically added to the data model of the object. For instance, a user object stores the answer of the user to a campaign in a dedicated custom field; whereas a device object stores the execution status of a remote action on another custom field. There is a limit on the total number of custom fields that campaigns and remote actions can add to the system.
Campaign
3 fixed + 1 per question + 1 per optional text
0, if embedded in a remote action
500
Remote action
6 fixed + 1 per output
3000
Because of performance reasons, there is also an additional limit on the number of campaigns and remote actions that can be simultaneously enabled. Regarding campaigns, note that the limit on the usable custom fields may be more restrictive than the limit on the number of campaigns themselves. In the case of remote actions, the limit affects only automatically triggered remote actions and the number depends on the frequency of the action.
Campaign
15 one-off or recurring campaigns
15 continuous satisfaction measurement campaigns
100 manual campaigns
1000 embedded (in remote actions) campaigns
Remote action
60 automatically triggered
30 out of the previous 60 with period < 1 hour
10 out of the previous 30 with period = 1 min
Portal content
The maximum number of modules, dashboards and widgets is not specified.
Accounts and hierarchies
The maximum number of user accounts supported by a Nexthink setup is 500 users. There is no specified limit on the maximum number of profiles and roles associated to the user accounts, but they are known to be higher than the following values:
Profile
> 300
Role
> 400
Similarly, there is no specified limit on the number of hierarchies and levels that can be created, as long as they do not exceed the maximum supported complexity in Portal. Contact Nexthink Support for more information.
The maximum length of the names that you can specify for user accounts, profiles and roles is as follows:
Username
128 characters
Profile
256 characters
Role
25 characters
The password length of internally managed accounts (that is, not provisioned from SAML or Active Directory) has the following limits:
Password
8 characters
25 characters
The minimum number of characters can be changed. Contact Nexthink Support for more information.
Entities and nodes
The maximum total number of entities in a Nexthink setup is 8,000 entities, which can be distributed among Engines with a maximum of 500 entities per Engine.
The maximum number of rules that can be specified in the CSV file to define entities is 1'000 rules per entity.
The maximum length for the names of entities and nodes is 50 characters.
Entity
50 characters
Node
50 characters
Finder (classic)
Investigations
There is no specified limit on the number of investigations that can be created in Finder. Related to investigations, the maximum number of results shown by a cross-Engine investigation is 10'000 entries (this can be overcome by exporting the results of the investigation).
The maximum query time of an investigation is 900 seconds (15 minutes). After that, Engine aborts the query.
Network and Web activity views
The maximum number of connections or web requests that can be visualized in the Network and Web activity views is 10'000 connections or requests per view.
