First time posting and hopes that someone can assist. Been using Subscription version of Observium for over 10 years collecting data on over 150 server farm using it daily and have been asked to now add monitoring of Windows Services.
I started to do this via Probes and SNMP checks but due to the shear volume of services and servers involved this would be a tedious process. I would like to use WMI to monitor Windows Services as it appears to poll faster. Unfortunately I ran into an issue where it only displays 3 services at a time. Windows Server has over 200 services by default, I don’t plan on monitoring all of them but at least a couple dozen. Using WMI would be a much easier way to setup alerts if I could get the full listing to appear, which is where I am needing help. Here is my setup to reproduce the issue (generalized information used for security) Follow the WMI setup in the help documentation for my UB 22.04 server Global Settings > Polling > WMI (turn on) Server discovered via SNMP Open Properties of Server and edit WMI information (per server polling only no global settings) WMI Hostname = nacn_ip_TCP:hostname.domain.local[sign] WMI Domain= domain WMI Username = username WMI Password = password After a couple of minutes, I get the results of only showing 3 services not a full list. AllJoyn Router Service Remote Desktop Service Themes I have tried this on multiple servers and the same 3 services appear each time. I began to look into the code and run the wmic query on the web server itself using the following query wmic -U “domain\username%password” //ncacn_ip_TCP:hostname.domain.local[sign] “select DisplayName, Name, State, Status from Win32_Service” It gave me the full listing results and from what I can see this is where the issue lies. CLASS: Win32_Service DisplayName|Name|State|Status AllJoyn Router Service|AJRouter|Stopped|OK Application Layer Gateway Service|ALG|Stopped|OK Application Identity|AppIDSvc|Stopped|OK … Telephony|tapisrv|Stopped|OK CLASS: Win32_TerminalService DisplayName|Name|State|Status Remote Desktop Services|TermService|Running|OK CLASS: Win32_Service DisplayName|Name|State|Status Themes|Themes|Running|OK Storage Tiers Management|TieringEngineService|Stopped|OK … The first item of the WMI services is the AllJoyn Router Service, then about halfway down the listing it produces a different CLASS:Win32_TerminalService and the headers. Then it has Remote Desktop Services and starts again with CLASS:Win32_Service and headers again, and the third entry to be displayed Themes. Looking through the code I think the issue resides in the /opt/observium/includes/wmi.inc.php code and the function wmi_parse. This is the function that is used (from what I can back trace) for performing the parsing of the WMI call and populating the database with the WMI entries. But when running the mysql query for the services listing it only shows these 3 listed and not all the services that the manual query performed on the server displays. I would like to ask if someone can look into the WMI process and check the coding to allow the WMIC query to populate ALL the service results in the web site. As a separate test I also went into the Global Settings > Discovery > WMI AutoDiscoveryOptions and added in several services manually (list of 10) not including the Remote Desktop Services and the results I get on the Windows Services tab show the Remote Desktop Services. So the 2nd CLASS that appears for this service appears to be causing the issue. Any help is appreacited. _______________________________________________ observium mailing list -- [email protected] To unsubscribe send an email to [email protected]
