Richard Hsu 4 Report post Posted November 4, 2015 We request another way for Logic Monitor to gather information from Linux based systems besides SNMP. Using SNMP involves installing NET-SNMP so taking up additional storage space. It would be better if Logic Monitor had an option for monitoring Linux systems like we had using Sitescope. In Sitescope all it needed was SSH and a dedicated login credential for the system. The Monitor would connect to the Linux based system through SSH and run scripts pertaining to what aspects were monitoring on that system. Then stores the results to be displayed on the console. Similar to using WMI in Windows. 3 Quote Share this post Link to post Share on other sites
mnagel 95 Report post Posted July 8, 2016 I agree we need a non-SNMP method to monitor Linux, even if that entails deploying a collector on each server. Leveraging other tools like collectd would also be nice options. We have run into various environments where SNMP (even SNMPv3) is verboten due to perceived security concerns. Even if allowed, manually configuring SNMP on many servers to enable basic data collection seems like a bad plan. Quote Share this post Link to post Share on other sites
Martin Rausch 1 Report post Posted July 11, 2016 I would very much like to see this as well. If ssh based monitoring is to be supported it should support ssh keys as well as passwords. Quote Share this post Link to post Share on other sites
Sam Gendler 0 Report post Posted April 26, 2018 Are ssh keys supported yet? Better yet would be the ability to fetch an ssh key, by name, from a key management service such as those offered by AWS and others. I don't want to have to encode passwords into the logicmonitor interface, and I certainly don't want to have to leave a private key with access to all my production resources on my collector, but my collector runs on an ec2 instance that has an instance role assigned to it, so it would be trivial to give that role a policy which allows it to fetch a key by name. If the basic ssh functionality included in scripts were to include the ability to look up an ssh key, or could receive the output of a different data source (I could write a script to fetch the key easily enough), that would be ideal, since modifying every data source to use a different script would be a drag. This would give me the ability to use key-based authentication for ssh while still allowing me to do key management without having to update filesystems and logicmonitor properties. I could simply rotate in a fresh key in the key management service and everything would continue to function normally. Quote Share this post Link to post Share on other sites
Mosh 115 Report post Posted April 27, 2018 (edited) Could be done now using the Expect library (as is used by Config modules). I would still like SNMP as well, not to replace it. As we have black box Linux appliances too. Edited April 27, 2018 by Mosh Quote Share this post Link to post Share on other sites
Jake Cohen 0 Report post Posted June 19, 2018 There is now a collection of SSH based datasources for monitoring Linux: Linux_CPU_Cores, Linux_Block_DevicePerformance, Linux_Memory_Usage, Linux_Host_Uptime, Linux_Filesystem_Usage, Linux_CPU_Load, Linux_Network_TCPUDP, Linux_Network_Interfaces They work in tandem with the Linux_Monitoring_SSH PropertySource. These can all be added via the LogicMonitor DataSource Repository. Quote Share this post Link to post Share on other sites

Kerry DeVilbiss 0 Report post Posted June 26, 2018 FYI for those tracking here - I believe we are currently working on updated versions of these that will provide the ability to use SSH keys for authentication. Stay tuned ... ! Quote Share this post Link to post Share on other sites

Kerry DeVilbiss 0 Report post Posted December 3 Hey @SeanC, You should be able to pull down all the modules via the UI - they are all published to our core repository and start with Linux_SSH_* See https://www.logicmonitor.com/support/logicmodules/about-logicmodules/keeping-your-datasources-up-to-date/ for additional information. Let me know if you can't pull them into your account and we can share the locator codes, if need be(!) Cheers, Kerry Quote Share this post Link to post Share on other sites
SeanC 1 Report post Posted December 3 Hi Kerry I had a look there first and the only ones starting with 'Linux' in my list are: Linux Disk Inodes Linux_Sensors_Fans Linux_Sensors_Temperature Linux_Sensors_Voltage Do I need to look at a different server than v128.core.logicmonitor.com ?

Kerry DeVilbiss 0 Report post Posted December 3 (edited) They should be available for all accounts - I would try reaching out to our chat support - they should be able to help with this right away. If you run out of luck there, let me know and I can grab those locator codes for you. Thanks, Kerry * Just in case, I went ahead and grabbed these. FYI though, the latest/ greatest will always be the repository (!)

SeanC 1 Report post Posted December 4 Thanks Kerry, turns out my problem was er... me. I didn't realise that someone else had already added them and I wasn't aware they no longer appear in the repository if they're already added XD Quote Share this post Link to post Share on other sites
