This tool is a rewrite of ngxtop to make it more easily installed and hopefully quicker. For those unfamiliar with the ngxtop, it is a tool that helps you parse NGINX access logs and print various statistics from them regardless of format. It is currently not feature complete with the original version but it should have enough functionality to be usable.
For those who have Rust installed, you can download it from crates.io:
cargo install topngx
topngx 0.1.0 Garrett Squire <[email protected]> top for NGINX USAGE: topngx [FLAGS] [OPTIONS] [SUBCOMMAND] FLAGS: -h, --help Prints help information -n, --no-follow Do not tail the log file and only report what is currently there -V, --version Prints version information OPTIONS: -a, --access-log <access-log> The access log to parse -f, --format <format> The specific log format with which to parse [default: combined] -g, --group-by <group-by> Group by this variable [default: request_path] -w, --having <having> Having clause [default: 1] -t, --interval <interval> Refresh the statistics using this interval which is given in seconds [default: 2] -l, --limit <limit> The number of records to limit for each query [default: 10] -o, --order-by <order-by> Order of output for the default queries [default: count] SUBCOMMANDS: avg Print the average of the given fields help Prints this message or the help of the given subcommand(s) info List the available fields as well as the access log and format being used print Print out the supplied fields with the given limit query Supply a custom query sum Compute the sum of the given fields top Find the top values for the given fields
Some example queries are:
# Run with the default queries and format (combined). # Or use the --access-log and --no-follow flags if you do not want to read from standard input. topngx < /path/to/access.log # See the fields that you can use for queries. topngx info # Run a custom query. # The fields passed in can be viewed via the info sub command. topngx query -q 'select * from log where bytes_sent > 100' -f request_path bytes_sent < access.log
The original version could tail log files in real time. Currently topngx can not do this but I am exploring options on how this can be done. Ideally I could use some implementation that is able to be
Read from. There is also no option to filter the data but this could be added in the future. The original version allowed for automatic detection of NGINX configuration files, log file paths, and log format styles. topngx currently has command line options for these and may add this functionality in a later version.
If you find any other issues or features that may be missing, feel free to open an issue.
