Hi all,
I'm using LTTng ( kernel 2.6.29.1) and LTTV ( 0.12.20) to obtain
traces of an application running in a Blue Gene/P system.
This is a run with 4 cores for each node. When running "LTTV -m
textDump ..." to process the traces I get the following message:
** (process:1002): WARNING **: 1842089 events lost so far in tracefile
trace116/net_2 at block 90
Do you know how can I avoid this events to be lost and this message to
appear?
The message is very important, you don't want to lose it.
As for not getting it, you probably busted your buffer size.
trace116/net_2 <- this means that net of cpu3 had a buffer overrun.
The way I avoid that is by giving each channel more buffers.
lttctl -C -o channel.net.bufsize=$((1<<23)) something like this
should help a lot.
Thank you,
Alessandro
