We already have Lock, LWLock, Buffer, I/O and XLogs probes. I'd like to have the following probes, too. In my experience, they could be bottlenecks or consume much time in some situations. - idle in transaction - spinlock wait-and-retry - CPU: Trigger execution - CPU: Encoding conversion - Network: send() and recv() - smgr: lseek() calls - Tempfile reads and writes Regards, --- ITAGAKI Takahiro NTT Open Source Software Center -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
