memcached Logs

If you enable verbose modę, using the -v, -w, or -vvv options, then the information output by

memcached includes details of the operations being performed.

Without the verbose options, memcached normally produces no output during normal operating.

•    Output when using -v

The lowest verbosity level shows you:

•    Errors and warnings

•    Transient errors

•    Protocol and socket errors, including exhausting available connections

•    Each registered Client connection, including the socket descriptor number and the protocol used.

For example:

32: Client using the ascii protocol 33: Client using the ascii protocol

Notę that the socket descriptor is only valid while the Client remains

connected. Non-persistent

connections may not be effectively represented.

Examples of the error messages output at this level include:

<%d send buffer was %d, now %d Can’t listen for events on fd %d Can’t read front libevent pipę Catastrophic: event fd doesn't match conn fd!

Couldn't build response Couldn't realloc input buffer Couldn't update event Failed to build UDP headers
