# collectd-prv: stdout to collectd notifications
collectd-prv converts stdout from a process into collectd notifications,
optionally acting like a pressure relief valve during event floods.
## Usage
## Example
* script
```collectd-tail
#!/bin/bash
set -o errexit
set -o nounset
set -o pipefail
# plugin = tail
# type = syslog
# limit = 30 lines/second
tail -F $1 | collectd-prv --service="tail/syslog" --limit=30
```
```collectd.conf
LoadPlugin exec
Exec "nobody:nobody" "collectd-tail" "/var/log/syslog"
```
## Build
```
make
# Recommended: build a static executable using musl
./musl-make clean all
# select a different method for process restriction
RESTRICT_PROCESS=null
# musl: enabling seccomp process restriction might require downloading a
# copy of linux kernel headers
export MUSL_INCLUDE=/tmp
git clone https://github.com/sabotage-linux/kernel-headers.git $MUSL_INCLUDE/kernel-headers
./musl-make
```
