Silk Performer provides a pre-defined data source for monitoring the Apache Web Server on Unix/Linux based systems. The commands issued by the data source for querying Apache use Telnet in order to query the server status of apache. Therefore if Telnet is disabled on the server ,e.g. for security reasons, you will not be able to monitor Apache using Silk Performer"s pre-defined data sources. To resolve this issue you should do either of the following: Ask your system administrator to enable Telnet on the server. Use the Wget command instead of the default Rexec commands, for example in Performance Explorer go to: PRE-DEFINED DATA SOURCES | CUSTOM DATA | REXEC DATA Enter a Wget command for querying the Apache server status page like so: wget -q -O - http://hostname/server-status | grep "requests/sec" | cut -c5- | cut -d\ -f1 Add the rexec data source and press close Old KB# 17987
