nettl question

[Sundararajan Anandhan_1]

Hi ,

I am trying to run a trace and format it dynamically. Eventhough I specify the buffer size as 1024 , the trace drops packets

This is the error I am getting.

217) Warning: Dropped 1 events containing 340 bytes while capturing this data. To prevent dropping data in the future you may need to choose a larger input buffer size when capturing data with nettl.

This is the command I am trying.

nettl -tn pduin pduout -size 1024 -e ns_ls_ip | netfmt -n -F -N -c /var/adm/crash/nettl.conf | tee -a /var/adm/crash/nettlfmt.log

I guess , the buffer size option is applicable only with a logging file option. In that case , can I increase the tracemax more than 100 Megs ? Or Is there a way to increase the buffer size with dynamic formatting.

Thanks in Advance.
Regards,
Sundar.

If i recall correctly nntl create up to two files TRC0 and TRC1.

And i remember i had moved the inactive one to other to get a large trace ( > 3 files) .


Hope this helps.

Hi Carlos,

I did think of this option but Since I am running the trace for several minutes, it will be a pain to monitor and move the TRC1 file to other names. May be I should write a script to do that. Anyway , Thanks for your inputs.
