Hi Geeks,
I am using tcpflood for sending burst on rsyslog.
when i send 100000 messages in 2.3 second everything is fine but when i
increase number of messages like 110000, rsyslog receive only about 101000
and drop all rest of the messages. The impstat interval is 10 sec. My
rsyslog and tcpflood is on same machine. But behaviour is same if i use
tcpflood on other machine. How can i tune tcpflood for 500000 messages in 5
sec and rsyslog receive the same amount of messages.
Please guide me regarding this issue.
what are you doing with the messages?
what is your configuration?
what version of rsyslog are you running?
we have people who have tuned rsyslog to handle several hundred thousand
messages per second (and reports of someone hadling 1 million messages/sec), but
it depends on what version you are running, what you are doing with the
messages, what transport you are using, etc.
For example, if you are using UDP transport and have a poor DNS server, you
could be bottlenecked on the DNS lookups, if you are writing out to dynamic file
names, you could be bottlenecked there if you don't have a large enough
dynafilecache, if you are sending the data to a database, you could be
bottlenecked there.
