PCP: support for 'dynamic columns' added at runtime Implements support for arbitrary Performance Co-Pilot metrics with per-process instance domains to form new htop columns. The column-to-metric mappings are setup using configuration files which will be documented via man pages as part of a follow-up commit. We provide an initial set of column configurations so as to provide new capabilities to pcp-htop: including configs for containers, open fd counts, scheduler run queue time, tcp/udp bytes/calls sent/recv, delay acct, virtual machine guests, detailed virtual memory, swap. Note there is a change to the configuration file path resolution algorithm introduced for 'dynamic meters'. First, look in any custom PCP_HTOP_DIR location. Then iterate, in priority order, users home directory, then local sysadmins files in /etc/pcp/htop, then readonly configuration files below /usr/share/pcp/htop. This final location becomes the preferred place for our own shipped meter and column files. The Settings file (htoprc) writing code is updated to not using the numeric identifier for dynamic columns. The same strategy used for dynamic meters is used here where we write Dynamic(name) so the name can be setup once more at start. Regular (static) columns writing to htoprc - i.e. numerically indexed - is unchanged. 2021-07-11 01:11:29 +00:00			`#`
