             Summary: [patch] CLI: core show fd: add timestamp
                 Key: ASTERISK-25405
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-25405
             Project: Asterisk
          Issue Type: Improvement
      Security Level: None
          Components: Features
    Affects Versions: Feature Tracker
            Reporter: Alexander Traud
            Severity: Minor


Thanks to "core show fd" on the command-line interface (CLI) of Asterisk, you are able to track open file descriptors:

{noformat}
./configure
make menuselect.makeopts
./menuselect/menuselect --enable DEBUG_FD_LEAKS
make --jobs
sudo make install
{noformat}

This helped me to find leaked UDP/TCP ports. However, when you debug a long-lived server with Wireshark in parallel, you need the time when the port (file descriptor) was opened. Therefore, I propose this as a feature request. The attached patch adds this feature.

Additionally, it fixes a formatting issue when very long source-code file-names are involved (15->22) because "channel_internal_api.c" was the longest seen. Finally, it changes "getrlimit" to return not the maximum size of a single file ({{RLIMIT_FSIZE}}) but the maximum amount of files which can be created by Asterisk ({{RLIMIT_NOFILE}}). For example in Debian/Ubuntu, I got "unlimited" with the previous code, although I expect the default "1024" file handles.
