Hi,
I have written a small code in C to poll switchs in a fiber optic
network. I must get counters values on this switchs for each port. I
have threaded the code in order to be able to poll 200 switchs in
some minutes.
I notice that with more than 4 threads I have a lot of SNMP timeout.
It's quite strange because the machine source is on a recent Blade
Center, the network is fiber and the switch are quite strong.
I poll one switch with one thread. With 5 threads I poll 5 switchs at
the same time.
For the moment I just have 8 switchs on all network and I poll only
one port counter for each switch.
I use :
snmp_sess_init( &session );
session.timeout = 2000000;
session.retries = 5;
session.version = SNMP_VERSION_2c;
snmp_synch_setup(&session);
sess_handle = snmp_sess_open(&session)
snmp_sess_synch_response(sess_handle, pdu, &response)
snmp_synch_reset(&session);
snmp_sess_close(sess_handle)
Is there something I miss?
