API Groovy HttpPatch?
Is it possible to do an HttpPatch, or to use the PATCH verb, when updating devices? I looked over on one of the LM pages for updataing devices with the API and as usual, most of the examples were in Python, but PUT did have one Groovy example, but PATCH did not. I’ve seen mention somewhere that at some point PATCH would be supported, wondering if it is or not. I ended up getting my script working with a Get (so I dont lose all my device custom settings etc) and then changing theautoBalancedCollectorGroupId value, and then doing a PUT and it worked, and I didnt lose any of my custom properties. And I have a working filter all set up to run it against a target set of devices. But still, I would rather just patch the fields I want without risk. I’m wondering if thats possible, or if GET/tweak/PUT is still the main go-to?Solved67Views9likes9CommentsOracle jdbc JAR file update
LogicMonitor's collector utilizes an outdated version of the Oracle JDBC jar file. It's essential to upgrade to the most recent version available in the Maven repository to take advantage of new secure database connection types. However, users should note a significant change in behavior with the new jar: while the old version automatically closed abandoned Oracle database connections, the new version does not, potentially leading to an excessive number of open connections. This surge in open connections can overload and crash an Oracle server where connections aren’t limited by user. Therefore, clients must either ensure that customizations explicitly close database connections or adjust their server settings to impose limits on the number of concurrent open connections. All of the newest Logicmonitor datasources properly close connections but some of the older modules did not do this. Logicmonitor has created a module to test for this problem and alert if it occurs. Oracle_Database_MonitorUser will keep track of the number of connections in use by the monitoring user and alert if the number of connections is too high. This update is scheduled for collector 35.400. Make sure this module is installed before upgrading to collect 35.400 and monitor your database connections before rolling this out to general release.61Views15likes0Comments
Windows Services Monitoring with quite a bit more Automation applied
So today we use LM's Microsoft Windows ServicesDataSource to monitor Windows Services. This DS uses Groovy Script and WMI calls under the hood to fetch the service metrics like state, start mode, status, etc... Everything works fine but one of the prerequisites is to go and manually populate the list of Windows services which then the DS parses out as a WILDVALUE variable in the script. You know, go to the device, click on Down Arrow (Manage Resource Options) --> Add Additional Monitoring --> and CHOOSE from the list of Windows Services. Rinse and Repeat and Save. Then the DS goes to work. Well, what if you have a list of over 100 Windows Services you need to add to let's say 20 Windows devices? That would take forever to populate that list manually... That's a problem number 1. Scratch that. This is not really a problem since one can run a PowerShell script (or Groovy Script) to perform this task using undocumented - but working very well - LM API calls. That problem is solved. Next - This list of over 100 Services needs to be *refreshed* every let's say 24 hours to remove nonexistent services and add new ones based on the Regex filter. That's a problem number 2. And again, one can do it programmatically running API calls but this is where I am trying to figure out how to do it. Run my script as a custom PropertySource? I am not really writing Resource Properties, I am updating instance list (Windows Services) within Additional Monitoring on bunch of Resources. Plus PropertySources are applied when ActiveDiscovery is run which is what, every 24 hours? Or should I write custom DataSource that would accomplish this refresh and specify 1 day collection period? Thanks.Solved159Views4likes2CommentsDoes anyone have any experience with monitoring Windows Processes?
I’ve checked the community for datasources and I don’t see anything to what I’m specifically looking for. Our organization currently utilizes the Microsoft_Windows_Services datasource (modified a little bit for our specific needs) to monitor services. I’m looking for something similar to monitor windows processes. Similar to the Microsoft_Windows_Services datasource, what I am hoping to accomplish is provide a list of keywords that will either match or be contained in the process name that I want to monitor, provide a list of machines that I want to monitor those processes on, andthen get alerted on if those processes stop running. Some issues I am running into so far are: Win32_Process always returns a value of NULL for status and state. So I cannot monitor for those two class level properties. Powershell’s Get-Process does not return status or state, rather it just looks for processes that are actively running, so I would need to get creative in having LogicMonitor create the instance and what value to monitor in the instance. Some of the processes I want to monitorcreate multiple processes with the same name, and LogicMonitor then groups them all together into one instance, which makes monitoring diffucult. Some of the process I want to monitor are processes that only run if an application is manually launched, which means that again I will need to get creative in how I set up monitoring because I don’t want to get alerts when a process that I know shouldn’t be running is not running. Because the processes I am trying to monitor are not going to be common for everyone everywhere, something that other people could do to try to replicate my scenario would be: Open Chrome. When Chrome is launched, you will get a processed called “Chrome”. Now, open several other tabs of Chrome, you will just get more processes named “Chrome”. Now, keeping in mind the points I made earlier, set up monitoring to let you know when the 3rd tab in Chrome has been closed, even though the rest of the Chrome tabs arestill open. How would you break that down? My first thought would be to monitor the PIDs, however, when you reboot your machine, your PIDs will likely change. Also, I don’t want to have the datasource wild value search by PID, because that would get confusing really fast once you have 2 or 3 different PIDs that you want to monitor. All suggestions are welcome, and any help is greatly appreciated. Bonus points if you can get this to work with the discovery method as Script and you use an embedded Groovy or Powershell script.Solved292Views12likes19Comments
Testing groovy script on local ubuntu machine
I am searching for a way to run groovy scripts on my local ubuntu (WSL) while being able to work with the same classes that are used by the collectors. To achieve this I installed a java+groovy and deployed a collector. However I am unable to import the classes like“com.santaba.agent.groovyapi.snmp.Snmp” Is there any way to achieve this? Or can I somehow locally access the collector shell to test groovy code without the need to use the LM web UI? So, I am basically searching for a way to develop scripted DataSources using CLI, without fiddling with the web UI. Any guidance very much appreciated.Solved146Views17likes9CommentsGroovy IDE recommendations for DataSource/ConfigSource development?
As I develop more and more ConfigSource and DataSource items in our portal, I find that I’m pretty hampered at times by the limited window space. Maybe its been silly of me all along to be developing in that window. But I’m wondering if anyone here has a recommendation on a Groovy IDE …. I havent researched yet so I dont know if there are multiple ones, or just one main one people use. But I’m wondering if any of you have suggestions on the best IDE, or if there are some ways to make sure the IDE environment is as similar to the ConfigSource window in terms of which imports are needed or available etc. Any advice on a best IDE or best practices for developing Groovy for LogicMonitor on the regular? Thanks!Solved103Views7likes4Comments
Entering enable mode using JSch
Does anybody have any example code on how to enter enable mode when using JSch? I already have the script working for 95% of my devices, so i don’t want to have to switch to expect. The channel mode is currently exec, which i think is the issue. It’s trying to execute `enable\n${enable_pass}\n${cmd}` all at once and the device is choking on it. Would rather not have to switch to shell mode, but if there’s no way to do it without shell mode, i guess i’ll have to take a stab at it.Solved112Views12likes3Comments
LogicModule development: script editor line numbers
Great news! LogicMonitor is finally adding line numbers to the groovyscript editor. Only joking. It’s STILL rubbish and there are no plans to fix it. When pairing LogicModule development I STILL have to say “up about 6 lines”, “no not that line”and “down a bit” every few seconds.Solved86Views14likes10CommentsSAP_HANA_SystemDatabaseAvailability Test DataSource Script failed
