I recently upgraded to PFSense 2.3.1 and one of the things that I missed was the old RRD graphs. The replacement is called Monitoring, which does a pretty good job, but I think we can do better. Our solution will be installing telegraf on the PFSense and running InfluxDB on another box.
Here is my configuration details:
InfluxDB IP: 10.5.5.40 InfluxDB Username: influxdb InfluxDB Password: influxdb Router IP: 10.5.5.1
First we need to prepare the router, lets
ssh into our router.
Then enter the shell:
*** Welcome to pfSense 2.3.1-RELEASE (amd64 full-install) on pfSense *** WAN (wan) -> vmx0 -> v4/DHCP4: x.x.x.x/23 LAN (lan) -> vmx1 -> v4: 10.5.5.1/24 0) Logout (SSH only) 9) pfTop 1) Assign Interfaces 10) Filter Logs 2) Set interface(s) IP address 11) Restart webConfigurator 3) Reset webConfigurator password 12) pfSense Developer Shell 4) Reset to factory defaults 13) Update from console 5) Reboot system 14) Disable Secure Shell (sshd) 6) Halt system 15) Restore recent configuration 7) Ping host 16) Restart PHP-FPM 8) Shell Enter an Option: 8
Install Telegraf (note you need to adjust the version to something newer):
[2.3.1-RELEASE][root@pfSense.localdomain]/root: pkg add \ http://pkg.freebsd.org/freebsd:10:x86:64/latest/All/telegraf-0.12.1_1.txz
After it installs you need to configure it to be startable:
echo 'telegraf_enable=YES' >> /etc/rc.conf
Now we need to update the
telegraf.conf connection information and what metrics we want to log:
cd /usr/local/etc vi telegraf.conf
[[outputs.influxdb]] urls = ["http://10.5.5.40:8089"] ... database = "telegraf" ... username = "influxdb" password = "influxdb"
Note: I didn't change any of the metrics that we are collecting and just using the defaults that came with the installation.
Now lets start
cd /usr/local/etc/rc.d ./telegraf start
Now you should be able to go
http://10.5.5.40:8083 and do a query for
SHOW DATABASES and see
In my next tutorial I'll show you how to do some queries to get useful data. If you are eager to jump ahead look here.
