| | | | | The default htop command process field has the enum identifier `COMM` but the name `Command` (`COMM` is the field name for /proc/<PID>/comm).

* Dynamically scale the ST_UID size to support 32-bit UIDsSilke Hofstra2021-10-271-2/+2
| | | | | | | | | | | | | | | | | | While most Unix-like systems use 16-bit user IDs, Linux supports 32-bit UIDs since version 2.6. UIDs above 65535 are used for UID namespacing of containers, where a container has its own set of 16-bit user IDs. Processes in such containers will have (much) larger UIDs than 65535. Because the current format strings for `ST_UID` and `USER` are `%5d` and `%9d` respectively, processes with such UIDs lead to misaligned columns. Dynamically scale the `ST_UID` column and increase the size of `USER` to 10 characters (length of UINT32_MAX) to ensure that the user ID always fits. Additionally: clean up how the titlebuffer size calculation and ensure the PID column has a minimum size of 5.

* PCP: support for 'dynamic columns' added at runtimeSohaib Mohamed2021-08-133-6/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Add a new DynamicMeter class for runtime Meter extensionNathan Scott2021-07-073-3/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit is based on exploratory work by Sohaib Mohamed. The end goal is two-fold - to support addition of Meters we build via configuration files for both the PCP platform and for scripts ( https://github.com/htop-dev/htop/issues/526 ) Here, we focus on generic code and the PCP support. A new class DynamicMeter is introduced - it uses the special case 'param' field handling that previously was used only by the CPUMeter, such that every runtime-configured Meter is given a unique identifier. Unlike with the CPUMeter this is used internally only. When reading/writing to htoprc instead of CPU(N) - where N is an integer param (CPU number) - we use the string name for each meter. For example, if we have a configuration for a DynamicMeter for some Redis metrics, we might read and write "Dynamic(redis)". This identifier is subsequently matched (back) up to the configuration file so we're able to re-create arbitrary user configurations. The PCP platform configuration file format is fairly simple. We expand configs from several directories, including the users homedir alongside htoprc (below htop/meters/) and also /etc/pcp/htop/meters. The format will be described via a new pcp-htop(5) man page, but its basically ini-style and each Meter has one or more metric expressions associated, as well as specifications for labels, color and so on via a dot separated notation for individual metrics within the Meter. A few initial sample configuration files are provided below ./pcp/meters that give the general idea. The PCP "derived" metric specification - see pmRegisterDerived(3) - is used as the syntax for specifying metrics in PCP DynamicMeters.

* don't include offline CPUs in summary for OpenBSDStuart Henderson2021-04-182-2/+30
| | | | | | | | | | By default, OpenBSD disables SMT (hyperthreading) cpu pseudo-cores. This can be changed at runtime by setting the hw.smt sysctl so they may become active later, therefore they are still present in cpu stat structures but are marked as offline. As done with native top(1), this drops them from the cpu summary graphs.
* Rework TTY columnChristian Göttsche2021-04-142-4/+12
| | | | | | | | | | * Rename internal identifier from TTY_NR to just TTY * Unify column header on platforms * Use devname(3) on BSD derivate to show the actual terminal, simplifies current FreeBSD implementation. * Use 'unsigned long int' as id type, to fit dev_t on Linux. Only on Solaris the terminal path is not yet resolved.
* Request the realtime and monotonic clock times once per sampleNathan Scott2021-04-051-0/+9
| | | | | | | | | | | | | | | | Refactor the sample time code to make one call to gettimeofday (aka the realtime clock in clock_gettime, when available) and one to the monotonic clock. Stores each in more appropriately named ProcessList fields for ready access when needed. Every platform gets the opportunity to provide their own clock code, and the existing Mac OS X specific code is moved below darwin instead of in Compat. A couple of leftover time(2) calls are converted to use these ProcessList fields as well, instead of yet again sampling the system clock. Related to https://github.com/htop-dev/htop/pull/574

* Move libcap use to (Linux) platform-specific codeNathan Scott2021-03-221-0/+4
| | | | | | | | | | | | The libcap code is Linux-specific so move it all below the linux/ platform subdirectory. As this feature has custom command-line long options I provide a mechanism whereby each platform can add custom long options that augment the main htop options. We'll make use this of this with the pcp/ platform in due course to implement the --host and --archive options there. Related to https://github.com/htop-dev/htop/pull/536

* Separate display from sampling in SysArch and Hostname MetersNathan Scott2021-03-041-0/+9
| | | | | | | | | Several of our newer meters have merged coding concerns in terms of extracting values and displaying those values. This commit rectifies that for the SysArch and Hostname meters, allowing use of this code with alternative front/back ends. The SysArch code is also refined to detect whether the platform has an os-release file at all and/or the sys/utsname.h header via configure.ac.
* Fix integer sizing issues in the NetworkIO MeterNathan Scott2021-03-012-12/+4
| | | | | | | | | On Linux kernels the size of the values exported for network device bytes and packets has used a 64 bit integer for quite some time (2.6+ IIRC). Make the procfs value extraction use correct types and change internal types used to rate convert these counters (within the NetworkIO Meter) 64 bit integers, where appropriate.
* [#480] SysArchMeter to view kernel/arch infoahgamut2021-01-311-0/+2
| | | | | | | At start, SysArchMeter calls the uname function to obtain the kernel version and architecture. If available, the distro version is obtained by calling lsb_release. The obtained values are stored in static variables and used when updating the meter.
