Feature Highlight: Dynamic Thresholds (Phase Two)
Note: Dynamic thresholds phase two will be activated for all Enterprise customer portals on July 16. At this time, if you currently have dynamic thresholds enabled for any datapoints, the new phase two functionality will automatically be enabled for those datapoints as well. Visit Enabling Dynamic Thresholds for Datapoints for more information on the enhancements and features included in phase two.
Last November, LogicMonitor released phase one of our AIOps Early Warning System. In this first phase, we brought you dynamic thresholds and root cause analysis. As part of our phase two efforts, we’re expanding the capabilities of dynamic thresholds.
In phase one, dynamic thresholds suppressed alert notification routing if the alert’s triggering value was not deemed anomalous by our anomaly detection algorithms. In other words, alert notifications that represented data values that fell within expected data ranges were automatically suppressed for the purpose of reducing alert noise.
With the enhancements available in phase two, dynamic thresholds now also automatically alert on values that fall outside expected data ranges.
By building upon our ability to recognize and proactively act upon anomalous data, we’re giving you the best of both worlds:
- Reduced noise when static datapoint thresholds aren’t tuned well (through notification suppression)
- Earlier alerting of issues that haven’t yet been (or perhaps never will be) caught by static datapoint thresholds.
- Improved alert clear behavior.
- An alert clear notification is now delivered when Active Discovery removes the DataSource instance that triggered an alert (due to the instance no longer existing). Previously, the alert was removed and an alert clear notification was not sent if the instance was removed, resulting in orphaned tickets in third-party applications.
- Previously, if an alert severity change and an alert clear took place within the same alert scanning cycle, alert clear was not successful, resulting in orphaned tickets in third-party applications. This has been fixed.
- Logging of device group moves. Previously, the action of moving a device group was not adequately logged in Audit Logs. Now, details for the removed/added parents of the group are added to the Audit Logs.
- Collector EA 29.100. LogicMonitor recently released a new EA Collector version. Highlights include:
- XL and XXL size collectors for 16 and 32 GiB of RAM.
- Collector Script Cache to allow caching of session tokens between collection intervals, without storing on the filesystem.
- Ability to migrate a Collector running as root or Administrator to a non-root or non-Administrator user.
- TinyRADIUS Java Library inclusion.
See EA Collector – 29.100 for more details.
- Table widget. Range fields for non-percentage values are now enabled and colored relatively, based on previously defined colors.
- Alert List widget. If an Alert List widget cannot render due to the use of too many filters in its configurations, users are now notified with the following descriptive error message: “Too many predicates supplied to filter query. Try simplifying your filter.” Previously, “unknown error” was returned.
- Multi-paged table editing. Fixed an issue with the EventSource definition editor (available under Settings | LogicModules | EventSources ) where, if the list of Collector attributes was long enough to become multi-paged, editing the nth item on one page would cause the nth item on another page to be unintentionally edited.
- AWS updates:
- Tagging support for AWS Glue and AWS Kinesis Firehose. Updated discovery filter tagging support in LogicMonitor to include AWS Glue and AWS Kinesis Firehose. This allows you to use tags to filter instances of the services in both the included instances and grouping/monitoring capabilities.
- AWS discovery filter tagging. Updated the LogicMonitor UI to properly reflect the AWS services that allow and do not allow discovery filtering based on AWS tagging. The UI listing had become out of sync.
- GCP updates:
- Device naming. There was an error in some GCP services that occurred when GCP scanning was done. Specifically, some instances received invalid device names that prevented them from being updatable. This has been fixed.
- Microsoft Azure updates:
- Learned routes available for Azure Virtual Network Gateways. A new property, named azure.learnedRoutes, is now discovered for Azure Virtual Network Gateways. This property shows the gateway’s learned routes.
- Peered connections available for Azure Express Route Circuit Peerings. Added peered connection names and IDs as properties, named auto.properties.peeredConnectionsName and auto.properties.peeredConnectionsIds respectively, for Azure Express Route Circuit Peerings.
- Azure subscription name. Added Azure subscription name as a property, named system.azure.subscriptioname, for instances. This is a more intuitive property than subscription ID. You can filter or group instances by this property.
- Technology provider logos. The Public Repository tab now displays technology provider logos, when available. Logos are displayed in both the grid and list views.
- Results Per Page setting. All three areas of the LM Exchange interface (Installed Modules, My Repository, and Public Repository) now feature a Results Per Page setting that allows you to change the default number of results from 25 to 50 or 100, depending on the interface. Updates to this setting persist on a per-interface, per-user basis.
- Safe LogicModule Merge (SLM). Fixed an issue that was causing SLM to incorrectly identify differences for datapoints whose names differed only in capitalization.
- Find Locator filter. Fixed issue where attempting to find an invalid LM Locator code using the Find Locator filter would lead to an endless spinning cursor.
- Test Active Discovery. Testing of the Active Discovery process from a DataSource definition, as initiated by the Test Active Discovery button, was failing with a vague error message. This has now been fixed and Active Discovery testing is working as expected in LM Exchange.
- Improved labeling on anomaly detection graph. The Show Alert Threshold option that is available when viewing the anomaly detection version of a graph now only shows effective thresholds. Previously, inherited thresholds were also displayed, which caused confusion and made it difficult to compare the expected range with the active (effective) threshold.
- New IP version filter. Enhanced NetFlow filtering UI to support future functionality.
- Improved handling of negative and rollover values. We have enhanced the platform backend to better log and filter out rollover and negative values sent from NetFlow devices.
- Disabled the storage of local GCC configuration. Previously, the GCC client saved GNU Compiler Collection (GCC) contents to a local file on the server for NetFlow monitoring. This storage process has been deemed unnecessary (and has been disabled) as GCC data is always available from the library.
- Interface Bandwidth report. Previously, not all instances were being pulled into this report for evaluation. This has been fixed.
- Resource Metric Trends report. A Scale by units of 1024 checkbox has been added to this report’s configurations, allowing you to more accurately evaluate instance disk storage on a scale of 1024 instead of the default unit scale of 1000.
- Fixed filter operations for properties collection. The filter condition (specifically not equal to) now applies correctly on all property values and not any one of the values as it was previously.
- Miscellaneous security fixes and improvements. Various security fixes and improvements are being released with this version.
- Bulk mapping. When creating or editing topology maps from the Mapping page, you can now add multiple vertices (resources) to a map at once. Previously, resources could only be added individually. This new functionality supports (1) bulk adding of multiple (or all) resources in a group and (2) bulk adding of multiple (or all) instances on a resource.
- Improved display of vertex resource details on Topology Map widget. Previously, the resource detail popup dialog would overlap other dashboard elements when opened from an unexpanded Topology Map widget. To prevent this, resource details for a vertex can only be opened when the Topology Map widget is expanded.

- Elimination of
percent()function use in complex datapoints. In an upcoming release, LogicMonitor intends to add validation for the purpose of preventing the use of the
percent()function within complex datapoint expressions. This function is intended to produce a percentile value, but requires data for multiple timestamps to do this. As such, it only works properly in virtual datapoints and its use within complex datapoints introduces ambiguity. As part of this initiative, we will also remove any existing complex datapoints that reference this method to ensure continuity in existing DataSource functionality.
Note: If you are using this function in the snmp64_If- DataSource, we recommend updating to the latest SNMP_Network_Interfaces DataSource (released in v.136), which uses Groovy to automatically handle this logic outside of complex datapoints.
- Originating IP address updates for SiteMonitor. Beginning with v.137 (and ongoing), LogicMonitor is updating the originating IP addresses for our SiteMonitor service, which consists of external testing locations used for Web Checks and Ping Checks. All potential IP addresses are listed in LogicMonitor’s External Testing Locations. Please ensure that your network’s firewall(s) permits access to all IP addresses on this list in order to maintain continued service.
