Migrate your Linux collectors to non-root by Sept 30!

Hello All, Thank you for supporting LogicMonitor's efforts to ensure Collector Security. With your help, we have been able to transition ~7,000 collectors to non-privileged users out of the 10,000 linux collectors currently live in customer environments. Per our last email on this topic, we had shared a deadline of June 30, 2023 for customers to migrate their collectors from root to non-root users. Due to customer requests needing more time, we have now extended the deadline to September 30, 2023, allowing for more time to test the non-root migration scripts and migrate linux collectors. We appreciate your support in helping us achieve our goal of running all collectors using non-privileged credentials. ACTION REQUIRED:Migrate any collectors which are running under root users to non-privileged users For more details, please refer to: https://www.logicmonitor.com/support/migrating-collector-from-root-to-non-root-user If your current collector installation process uses the root user t

Upgrade your Collectors to MGD 33.006 before October 03, 2023!

Each year LogicMonitor rolls out the minimum required version (the MGD) for all collectors. It is the most mature version containing the gist of all the enhancements and fixes we’ve added throughout the year. To achieve uniformity, the MGD becomes the base version for all future releases. As we approach the time for the MGD automatic upgrade, we would like to inform you that the GD Collector 33.006 will be designated as the MGD Collector 33.006. This means that all collectors must be upgraded to GD Collector 33.006 or higher. Note: If it is absolutely necessary, we may release security patches. In such scenarios, the MGD version 33.006 will be incremented, and we will keep you informed. Schedule for MGD 33.006:MGD 33.006 Rollout: August 29, 2023 Voluntary upgrade time period: Anytime before October 3, 2023 Automatic upgrade Scheduled: October 3, 2023 at 5:30 am PSTPlease note that it is critical to upgrade to the new MGD version!

Logic.Monitor (PowerShell) module

If you're a LogicMonitor user looking to streamline your workflows and automate repetitive tasks, you'll be pleased to know that there's is a PowerShell module available to help you do just that. As a longtime Windows administrator, I've relied on PowerShell as my go-to tool for automating and managing my infrastructure. I've found that the ability to automate tasks through PowerShell not only saves time, but also reduces errors and ensures consistency across the environment. Developed by myself as a personal side project, this module provides a range of cmdlets that can be used to interact with the LogicMonitor API, making it easier than ever to manage your monitoring setup directly from the command line. Whether you're looking to retrieve information about your monitored devices, update alert thresholds, or perform other administrative tasks, this module has you covered. In this post, we'll take a closer look at the features and capabilities of this module, and show you how to get st

Monitor DFS Share(windows server) using LM Collector!!

Greetings to all members of the LM community. Hope you all are doing great!Our community blog in this section, discusses on how to monitor DFS share in LM & general recommendations to follow for our LM collector to monitor the share path in today's community blog: Configuring DFS share on Windows server :This DFS share service is dependent on two parameters to establish communication with the target server, shown below, as you can see from the target server:With these two parameters, domain name and IP are used to configure communication with DFS for the purpose of LM data collection.In my test environment, I've created a Stand-alone Namespace that has the following permissions on the local path:In addition to defining the local path permissions for a DFS share, you also have the option to edit the permission for the local path of the shared folder at the time of creating the share path : Pre-requiste/Permissions required : As well as permission, there may be other things the LM c

Sample Webcheck via Groovy Scripts to test-out!!!

In LM tool, you can choose to manually add your request and response Groovy scripts directly into the text boxes found under both of these Script tabs or, as shown next, you can choose to first complete the fields under the Settings tab (e.g. HTTP Version, Method, Follow redirect, Authentication Required, Headers, HTTP Response Format, etc.) and then click the Generate Script from Settings button to have LogicMonitor auto-generate request and response scripts based on those settigs.The latter option produces a basic template for your Groovy scripts. (For more information on completing the fields found under the Settings tab for both the HTTP request and response, see Adding a Web Check).So with LM platform tool, you can also auto-generate request and response scripts script as shown in above screenshot.Now here is an sample script to providing a code snippet in Groovy that's using the Santaba HTTP library to make an HTTP GET request to a specified URL (in this case, "https://www.google

Website monitoring with Zscaler client in LM

To monitor website access via Zscaler using LogicMonitor, you can set up web checks to verify if the websites are accessible and responsive. LogicMonitor's web checks allow you to periodically test the availability and performance of websites from different geographic locations. Here's how you can set up monitoring for website access via Zscaler:Pre-requisite You will need to have introduced the Zscaler client to the LM Collector Server placed in the network environment where Zscaler is used for communication to access the Internet via websites. Zscaler reference doc for more information : https://help.zscaler.com/zia/skipping-inspection-traffic-specific-urls-or-cloud-apps https://help.zscaler.com/zia/whitelisting-urls Our Collectors gather information from your infrastructure, encrypt it, and deliver  it to the LogicMonitor Service through an outbound TLS-encrypted connection, where it is stored, processed and presented back to users through a web interface.

SNMP Trap Credentials on Resource Properties Enhancement

Hello LM Community! Just wanted to highlight this enhancement that has been released recently in EA Collector 34.100 to support the use of SNMP trap credentials on resource properties.When using this collector version or newer, you can add snmptrap.* properties on resource/group level for the collector to decrypt the trap messages received from monitored devices. The credentials are used in the following order: Collector first checks for the set of credential snmptrap.* in the host properties. If the snmptrap.* credentials are not defined, it looks for the set of snmp.* in the host properties. If sets for both snmptrap.* and snmp.* properties are not defined, it looks for the set eventcollector.snmptrap.* present in the agent.conf setting. More details can be found in the below articles in our documentation:SNMP Trap Monitoring: https://www.logicmonitor.com/support/logicmodules/eventsources/types-of-events/snmp-trap-monitoringEA Collector 34.100 Release Notes: https://www.logicmonitor.

Common ConfigSource Documentation

Hello LogicMonitor community, I wanted to drop this here as it’s been something in the works for a long time. As I am sure many of your are all aware our development team has been working on and has actually released a new set of ConfigSources called “Common Configs”. These have been released into our core repository since late 2021 with support for more manufacturers and more features being added into these LogicModules throughout the last 2 years. The time has come that we have been able to get a support document around these Common Configs released with the requirements for them, optional parameters you can add to help them be successful, and the list of all currently released modules related to this suite. https://www.logicmonitor.com/support/common-config-monitoring

Monitoring folders on Windows servers

I was recently asked by a customer if it was possible to monitor the size of a folder or the file count in a folder on a Windows server. Well there sure is, <whistles> YO UNC Monitor- come on down.UNC Monitor- is part of the Core DS, the DSs that are installed by default when LogicMonitor is first deployed. As seen on the UNC Monitor Description section:Great, there is a way to do this. Ok how do I do this? Hmm? Well looking at the next section of the DS, Technical Notes. Add an instance manually, oooohh k. But how do I perform this specific voodoo? Hmm maybe if I look further down on the DS? Ok there is the Groovy Script, what do I get when I run the Test Script? Ok so I do have 5 folders that contain 41 files using a total of 7,013 KB. Great that’s some info but still not what I need for a path and I still don’t know how to “add the instance manually”Maybe there is some documentation on how to do this?

Docker Collector Deployment Improvements

This post will provide additional configurations not covered in the LogicMonitor “Installing the Collector in a Container” support guide. Docker specific documentation can be found here https://docs.docker.com/engine.This post will not cover the Docker specific configurations such as creating a network. Support Guide Docker Container Collector InstallationIf you follow the support guide linked above to deploy a collector in a Docker container, you will be able to monitor resources using the Docker collector. However, if you have deployed a collector in a Docker container, and only followed the support guide linked above, you may have noticed the following items:The collector container is deployed to the default bridge network and this is not recommended for production use cases. The collector container by default is not set to perform any restarts. The collector container is not assigned an IP upon startup which will impact how LogicMonitor identifies the collector container resource i

Feature enhancement: Preserve changes to alert thresholds when updating customized LogicModule

LogicMonitor continues to roll out more enhancements to the Module Toolbox to make viewing, updating, installing, and managing LogicModules easier than before. In release v186, it is now possible to preserve alert thresholds when updating modules to newer versions. This enhancement adds to the current ability to preserve Active Discovery filters, AppliesTo, Collection Interval, Discovery Interval, Display Name, and Group during module updates. These preservation options provide the benefit of our LogicModule team’s enhancements and fixes combined with your environment-specific customizations. To preserve your module’s alert thresholds when updating via the module Exchange, use the toggle on the right pane of the “Final Review” update window. Once you finish the module update, your alert thresholds will remain. Happy updating!Support article reference: https://www.logicmonitor.com/support/modules-management

LogicMonitor, Groovy, Python and APIs Ohhh my

You just started your new job and they have LogicMonitor as their observability tool, that’s great! One huge step up from other organizations you’ve worked with. The last guy that worked on the platform did a pretty good job of keeping up with the platform but you see some improvements that would really help with the organization of the portal. You want to create multiple folder structures. The first group of nested folders will be based on the equipment location the second will be based on the equipment task. This will allow you to provide additional people access to the portal but limit their visibility into only the things that are in their location or their job function. Yup sounds great, your coworkers like it and more importantly your manager approves. Now how are you going to assign 700 pieces of equipment at 30 different sites to the correct folder with the correct permissions? Oh yeah you got a secret weapon, APIs! The goal of this and subsequent posts is to try to d

A DataSource to Troubleshoot ERI Merging

One of the most common behaviours noticed in topology maps is ERI Merging. This is caused when two or more devices share the same identifier (ERI). The example I always like to give when I’m teaching Topology Mapping is the word “football”. To a European like myself this is a game played with your feet, however in other parts of the world this is an altogether different game. Now let’s imagine we have a Topology Map connecting various sports together; what would show up if the map connects “football” to “basketball” - would it be the kicking game or the throwing game? Well, in LogicMonitor, it would be effectively indeterministic to tell. The two games would merge into a single object in the map (they merge into one of the resources at “random”). A key indicator of merging is one device showing as another device in the topology map.Luckily, there are a few out of the box ways to overcome this merging - the topo.blacklist and topo.namespace properties. If you’re interested in finding ou

LM Synthetics

What is Synthetic Monitoring? Synthetic Monitoring is an active approach to testing a website or web service by simulating visitor requests to test for availability, performance, and function. Synthetic monitoring uses emulation or scripted recordings of user interaction or transactions to create automated tests. These tests simulate a critical end user pathway or interaction on a website or web application. The results of these tests give early insight into the quality of the end user experience by reporting metrics on availability and latency, and identifying potential issues. LM Synthetics monitoring leverages Selenium—a trusted open-source browser automation and scripting tool to send Synthetics data to LogicMonitor. LM SyntheticsLogicMonitor uses the following Selenium tools for the Synthetics monitoring solution: Selenium GRID—Proxy server that allows tests to be executed on a device Selenium IDE Chrome Extension—Browser recording tool that allows you to create and run th

Retrieving data from an external API via a Groovy Scripted module

1) Using Expert mode, define a resource as the hostname of the api in question, i.e. api.someapinamehere.com. For the purposes of this example, I'm going to make a call to worldtimeapi.org for data on the timezone America/Chicago to determine if daylight savings time is in effect. 2) Next, choose an available collector and group (optional) and click save. Note: normally you would also add your api user name (if any) and api token as properties, but in this case, it's not necessary. 2) Next, go to Settings -> LogicModules -> DataSources and click Add -> Datasource3) Follow the steps below to adjust the DataSource: 4) Insert this script in the text box entitled Groovy Script under Collector Attributes import com.santaba.agent.groovyapi.expect.Expect;import com.santaba.agent.groovyapi.snmp.Snmp;import com.santaba.agent.groovyapi.http.*;import com.santaba.agent.groovyapi.jmx.*;import org.xbill.DNS.*;import groovy.json.*; //Defines host as the name of the resource added, in this c
