I have to monitor Webserver (iPlanet), Appserver (Websphere) both of them are behind the firewall and the sysadmin doesn’t opens the port for monitoring even though we got the license and for monitoring over firewall they are not providing machines inside firewall (Monitoring machine) and outside Firewall (MI Listener). But I need to Monitor the servers, we can use vmstat and topstat for monitoring the system resources but I need to monitor the Bytes sent/sec, HTTP request rate, JVM memory, JDBC connections and others, which are specific to websever and appserver. So please suggest some other way to monitor these parameters.
Have you sat down with the System Admin and explained what you are doing and what your needs are? I have found that in similar situations, while they may not always be open to providing me access, they are often quite willing to perform the monitoring themselves and provide me with the results. Not the ideal way to do it and it certainly makes troubleshooting more difficult, but sometimes we have to "make do".
