rrdtool
- install rrdtool and python 3 version
- Create database
- Python script to read data to store (pipe into python then write to rrd)
  - RPI Stats - 10 sec - CPU usage %, Mem usage %, Disk %, CPU temp
  - GPS Stats - 10 sec - TPV and SKY lat, lon, alt, epx, epy, epv, xdop, ydop, vdop, tdop, hdop, gdop, pdop
  - GPS Sats - 10 sec - PRN 1-32 each with el, az, ss, used (0 or 1)
  - NTP stats - 16 sec - ntpq -c rv, offset, frequency, sys_jitter, clk_jitter, clk_wander
    - ntpq -p - PPS and GPS each offset and jitter
- rrdgraph for simple/recurrent graphs
- python export for more complicated plots
Python plot for NTP log files
Disable MRTG and instead use cron and rrdtool for plots
Plot NTP stats with MRTG - create perl/shell scripts to read data
- Jitter
- offset
Create GPS stats with MRTG - shell scripts to extract data
- NMEA sentence format http://aprs.gids.nl/nmea/
- GPS MRTG - https://www.satsignal.eu/raspberry-pi/monitoring.html#gps
- Sats visible
- DOP
- errors
- lat,long,alt
- gpspipe -r and search for GPGGA and GPGSA and parse for stats
CPU, Mem, wifi load, CPU temperature, storage
- Use SNMP OIDs or use a shell script directly
Copy all config files to this repo
- NTP conf
- GPSD conf
- SNMP conf
- MRTG conf
- apache conf
- website pages
Fix reload config script to move other config files
- snmp
- dhclient
- apache default website config
- gpsd
- ntp
- website files
Check on updating the leapsecond file (does NTP do it or do I need to do it)
Add current time to Index page with offset using php
Once time is working then join NTP pool - will need to do duckdns and port forwarding on router

NTP Best practices - https://tools.ietf.org/id/draft-ietf-ntp-bcp-06.html#rfc.section.4.4 To get ntp stats use ntpq -c rv then grep for desired data
