synology-nas-monitoring's Introduction

Synology NAS monitoring

The main points of this project are:

Persistence is supported via mounting volumes to a Docker container.
Grafana will store its data in SQLite files instead of a MySQL.
Added snmp packages and Synology NAS MIBS.
Enable

Enable SNMP

From Control panel in your Synology NAS go to Terminal & SNMP
Click on SNMP tab, and enable SNMPv1, SNMPv2 service
in Community input put public
Save

Run Docker image in your Synology

Install Docker from Synology package center
Create two empty folders in your Synology influxdb and grafana, we need to use it later to mount it to our container.
Open Docker client from Synology > Image > Add > Add from url and paste Hub page url "https://hub.docker.com/r/alhazmy13/telegraf-influxdb-grafana"
Wait until it finishes downloading the image
Click on the image "alhazmy13/telegraf-influxdb-grafana" and then click on Launch
Network Tab keep it in bridge mode
Check "Enable auto-restart."
Port settings, just change Local port for 3003 from Auto to 3003, and port 514 from Auto to 5144
In Volume settings, click Add folder and select the first folder that we created, "grafana" and on mount Path, paste /var/lib/grafana
In Volume settings again, click Add Folder and select the second folder that we created "influxdb" and on mount Path paste /var/lib/influxdb
[OPTIONAL] Environment Tab > Add new variable "TZ" with your local time zone ignore this if you want to use the default UTC
Apply, Next, Done and your container should be ready.

Start Grafana

Open http://YOUR_LOCAL_NAS_IP:3003 and login with the default username root and password root
You need to import the dashboard. To do this, go to http://YOUR_LOCAL_NAS_IP:3003/dashboard/import and put 14590 in "Import via grafana.com" input
Click on load and complete the process

Enable Logging

Install Log center From Synology package center
Open Log center app
Click on Log Sending > check "Send log to syslog server"
Set Server = localhost, port = 5144, Protocol = UDP, Format = BSD (RFC 3164)
For testing, click on "Send test log"
Apply

Configure Firewall

If the firewall is enabled, then you need to add a new rule for port UDP/161, This is mandatory otherwise, some data will be missing from the dashboard #7 .

Open Control panel
Security -> Firewall
Edit Rules -> Create New Rule
In the ports section, select from a built-in applications and chose SNMP service
In the IP section select Spesifc IP -> subnet -> Source: 172.12.0.0 / subnet: 255.255.0.0
Action = Allow
Disable and re-enable the firewall for it to take effect

influxdb crashing

Hi,
I installed everything as described in the readme. However, the container log is full of logs like (repeating every second):
INFO spawned: 'influxdb' with pid 6250 INFO success: influxdb entered RUNNING state, process has stayed up for > than 1 seconds (startsecs) INFO exited: influxdb (exit status 1; not expected) INFO spawned: 'influxdb' with pid 6269 INFO success: influxdb entered RUNNING state, process has stayed up for > than 1 seconds (startsecs) INFO exited: influxdb (exit status 1; not expected) INFO spawned: 'influxdb' with pid 6288 INFO success: influxdb entered RUNNING state, process has stayed up for > than 1 seconds (startsecs) INFO exited: influxdb (exit status 1; not expected)
It looks like influxdb is working, at least Grafana shows data.

After last update unable to pull information

Post upgrade to latest container where grafana was updates i am unable to get into influxDB.
Getting the below error when going to configuration and testing connection,

Get "http://localhost:8086/query?db=telegraf&epoch=ms&q=SHOW+measurements": dial tcp 127.0.0.1:8086: connect: connection refused error performing influxQL query

Here is a screenshot of what I see:

Some Data are missing

Hey thanks for the packeg.
Was very easy to set it up and looks very good but a few datas are missing:

Not sure if this ist due to DSM 7 or because i use the NVME SSDs as a second volume.

Any idea?

trouble accessing grafana after installation

I downloaded the image succesfully, and tried to launch it according to the instructions given. it seems to be up and running now, however when looking at the docker container logs, i can see its shutting down various services, meaning i am not able to access grafana because it is not running anyway. Is your system still operational?

docker-compose port 5144:514 needs /udp appending

As title. I provided the docker-compose file for you on Reddit, off the top of my head. Having run it, I realised that - 5144:514 needs to actually be - 5144:514/udp to function. Once this change is made, logging now works. Sorry for the mistake.

Wrong Temps of SYS on random syno....

Hello dear, why the system temp on my 918 shows 25C+ - degrees higher than the real. May be can add CPU Temp separeted?
Example:
echo "Case Temp";cat /sys/devices/platform/coretemp.0/hwmon/hwmon0/temp1_input
or multicore temps Examle:
echo "Core 1 Temp";cat /sys/devices/platform/coretemp.0/hwmon/hwmon0/temp2_input
echo "Core 2 Temp";cat /sys/devices/platform/coretemp.0/hwmon/hwmon0/temp3_input
echo "Core 3 Temp";cat /sys/devices/platform/coretemp.0/hwmon/hwmon0/temp4_input
echo "Core 4 Temp";cat /sys/devices/platform/coretemp.0/hwmon/hwmon0/temp5_input
best regards!

snmp v3

First, thank you so much for the incredible solution.
Second, Not a bug, but wanted to ask. Is there a way to use this with SNMP v3 vs v1/2 with public?
Thank you so much !

Grafana crashing

I had this successfully running on my Synology previously, but re-initialized the volume and cannot get it to work again. When following the directions on this repo I get the following logs from supervisord ad infinitum.

2022-12-20 04:11:10,233 INFO spawned: 'grafana' with pid 5185

Looking in the grafana log I see complaints about the database being locked initially:

Any idea what's happening? This was tested with the same result both on latest and develop.

Suggestion: Celsius to Fahrenheit

If you want the temperature gauges to show F instead of C:
Edit the gauge
Modify the unit from C to F (on the right bar)
Add math calculation of * 9 / 5 + 32 in the select field on to bottom side
Match to the image below
