Hi all: I am having problems with not getting data from Agent X master agent (snmpd). It is related to timeout and I am not sure what to do or where to start.
I have a sub-agent which I developed to monitor my application which consists of a set of software processes. I have instrummented my monitored application to return data when it receives request from sub-agent. Between sub-agent and my monitored application, I am just using regular socket C blocking-mode send/receive APIs and when I get data from my application, I will populate the MIB. I have a time out in my sub-agent.conf. I will wait for that amount of time after forwarding the request to my application. I am using MIB table, each row in the table represents one process, the key is PID. I am sending snmpwalk commands continously every <N> seconds. The processes I am monitoring are overloaded (busy doing their job). I have create a new thread in each of those processes to respond to the SNMP request. When the system is overloaded, my sub-agent times out, and I think eventually master agent times out too and I started getting the following errors for ever.!!! No Such Object available on this agent at this OID Note that at that time, snmpwalk commands are still being sent continuously AND the system is still overloaded (because I am giving heavy load to my application for stress test). In a situation like that what should I do to avoid those errors? Is it possible? Where do I start? For normal load testing, everything is fine. I don';t get those errors and my snmpwalk commands get expected data from my application. Any comment, idea, suggestion would be very much appreciated. If I am not clear in describing the problem, please let me know. Thanks in advance! Steve __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
