Our team is back after the the festival of lights ! This week let me tell you why you may get the sometimes annoying “Unknown category” servers. In applications manager when you add a new application or database for monitoring, the server in which that application is present will be also automatically added for monitoring. This server will be added under the Unknown category.
If SNMP agent is running in that remote server, applications manager will try to find the operating system of that server by querying that snmp agent ( it will query with community string as ‘public’ ). If applications manager gets proper response from the snmp agent, it will be added in the corresponding OS category and data collection will be initiated or that server will remain in Unknown category.
Applications manager will only check the availability of the servers under unknown category, it will not collect perform statistics ( like cpu utilization, disk utilization etc ). The user should manually edit and update the monitors with proper details under Unknown category to initiate full data collection. Similarly for other automatically discovered applications, if user has not provided proper credentials, applications manager will only check availability and response time for that application.
