Non-intrusive remote monitoring of data centre services should be such that it does not require (or minimal) modification of legacy code and standard practices. Also, allowing third party agent to sit on every server in a data centre is a risk from security perspective. Hence, use of standard such as SNMPv3 is advocated in this kind of environment. There are many tools (open source or commercial) available which uses SNMP; but we observe that most of the tools do not have an essential feature for auto-discovery of network. In this paper we present an algorithm for remote monitoring of services in a data centre. The algorithm has two stages: 1) auto discovery of network topology and 2) data collection from remote machine. Further, we compare SNMP with WBEM and identify some other options for remote monitoring of services and their advantages and disadvantages.
