Hello, Free- Options; 1- Nagios : Which requires too much effort to pring up i tired once but give up. 2- Pandora FMS: installation nice but after putting snmp libs was hard, i could not succeed. 3-ZenOss: once was my favourite becouse you can create scripts to automate task in linux enviroment based on alerts, it supports winrmc and winrms feature whic you can connect and take action in windows enviroment. 4-Ganglia and etc. was frusrating spending too much time on monitoring software not an option allways. My Suggest; Half Free option is PRTG 100Sensor is free, Download Prtg on windows server and install. Download PRTG MIB importer to your computer. Go to support page and downlod required MIB files, open PRTG MIB importer and import it. After import save odlib file to PRTG Server library. After Save go to prtg and add device without autodiscover (up to you you may want to try). open device in Prtg admin page then select add sensor. Then select custom library and find imported mib library file. And select required sensor for you. Have a nice day.
