![]() You need to first find process ID then use it to find elapsed time. You can use ps command to check the time a particular process has been running. Works just like the high threshold described above, but colors the timestamp bright instead. If the type is elapsed-line or elapsed-total, this option is ignored. f | -format="format": Format the absolute timestamp, using PHP date format strings. By default, gnomon will display the seconds elapsed between each line, but that is configurable.Įlapsed-line: Number of seconds that displayed line was the last line.Įlapsed-total: Number of seconds since the start of the process.Įxample: $ ping -c 3 8.8.8.8 | gnomon -type=elapsed-totalĠ.0049s PING 8.8.8.8 (8.8.8.8): 56 data bytesĠ.2336s 64 bytes from 8.8.8.8: icmp_seq=0 ttl=59 time=46.288 msġ.2798s 64 bytes from 8.8.8.8: icmp_seq=1 ttl=59 time=35.811 msġ.2801s 64 bytes from 8.8.8.8: icmp_seq=2 ttl=59 time=80.783 msġ.2805s 3 packets transmitted, 3 packets received, 0.0% packet lossġ.2821s round-trip min/avg/max/stddev = 35.811/54.294/80.783/19.213 ms It will indicate how long the process took to execute. To prepend a timestamp to each line, you need to pipe the command to gnomon. usr/local/bin/gnomon -> /usr/local/lib/node_modules/gnomon/bin/gnomonĪdded 56 packages in 13.076s Using Gnomon ![]() Once you have npm tool present on your Linux system, then proceed to install them using: $ npm install -g gnomon Since Gnomon is a tool written in Node.js, you need Node.js installed on your system so that you can install gnomon with npm package manager. ![]() This tool is useful for long-running processes where you'd like a historical record of what's taking so long.
