Below is a brief description of each job.

An interactive wrapper script for some of the more common/useful things you can do with this repo. Run support-tooling.sh from within an extracted support script and a simple menu will guide the user.

Summarize the count, average duration, and 99th percentile duration of per endpoint in Puppet server and DB access logs per 30 minute interval. Can also graph the count and average duration in gnuplot

top-api-calls.sh [-b] [-g] [-c] <access_files>
  -b uses the JRuby borrow time instead of overall duration
  -g plots the average durations in gnuplot
     -c can be used in combination with -g to plot counts

herd_plot.sh <herd_query_file>

Plots the results of the thundering herd query in gnuplot. TODO: summarize the data so it's more legible

partition_sum.sh [ -t <partition name> ] <path_to_db_relation_sizes_by_table.txt>

Outputs the total size of a partitioned postgres table, defaulting to resource_events. Currently, -t pe-puppetdb.reports is also supported.

$ partition_sum.sh -t pe-puppetdb.reports resources/db_relation_sizes_by_table.txt  | numfmt --to=si
29G

puppet_access_slowest.awk <path_to_access_log>

Prepend the desired field from the access logs (currently, %b for byte size of the payload and %D for the duration) to each line. Can be used in combination with other tools, e.g.

puppet_access_slowest.awk logs/puppetserver/puppetserver-access.log | sort -nr | cut -f2- -d ' ' | head

puppetdb_longest_queries.awk <path_to_puppetdb.log>

Calculate the average duration of a PDB command per node. Can be used in combination with other tools, e.g.

echo "Average Count Hostname" && puppetdb_longest_queries.awk logs/puppetdb/puppetdb.log  | sort -rn | head | column -t

Calculates the average catalog compilation time per node. Can be used in combination with other tools, e.g.

echo "Average Count Hostname" && puppetserver_longest_compiles.awk logs/puppetserver/puppetserver.log | sort -rn | head | column -t
