Hello, I have committed some code to allow easier troubleshooting and monitoring of PKG usage per process. One new functions are exported by cfgutils module: - pkg_summary() - can be used to dump summary of PKG usage Btw, there was also added shm_summary() that dumps the summary of SHM usage. The kex module exports a new rpc command 'pkg.stats' that prints PKG usage metrics (used, free, real_used) per process. Here is a sample output: sercmd> pkg.stats { entry: 0 pid: 4793 rank: 0 used: 124788 free: 3813512 real_used: 380792 } { entry: 1 pid: 4794 rank: 1 used: 132740 free: 3805512 real_used: 388792 } { entry: 2 pid: 4795 rank: 2 used: 132740 free: 3805512 real_used: 388792 } The adding free to real_used values results in pkg memory size per process (4MB in this example). To get these stats, you have to compile with MALLOC_STATS enabled (this is default for Kamailio, so nothing actually to do for it). One benefit of this pkg.stats is ability to monitor usage of private memory and trigger alerts if the amount of available memory (free) for one process goes below a lower limit, useful when there is a memory leak (so you restart in time and report the problem) or the config operations for given traffic needs larger PKG size. In the near future there will be some new additions to be able to access these values also via PVs. Testing and feedback is appreciated.
