## peshming
## rexaping
It's a prometheus exporter pinging hosts in the background.
It's been inspired by [meshping](https://bitbucket.org/Svedrin/meshping),
but instead of managing targets using a redis db this is using a simple config file.
In addition, this tool allows to set a ping frequency per target.
It's been forked from [peshming](https://git.jcg.re/jcgruenhage/peshming),
but only allowing targets to specify an interval, the config file can enrich
the Prometheus metrics with additional labels.
The name peshming is intended as a placeholder until
someone comes up with something better.
The name rexaping is a play on exaping, a tool with the same purpose
originally written in Python for Exa Networks.
### Usage:
```
$ peshming --help
peshming 0.2.3
$ rexaping --help
rexaping 0.2.3
Marek Isalski <marek@faelix.net>
