Hi there,
based on my ideas and findings from one of my previous posts, I have published my “health check script (linux + macOS)” on GitHub. 
Please feel free to support, subscribe or comment. I’ll release updates soon, in order to make it more self-descriptive and common to use for everyday usage.
Target group: docker and linux / macOS users.
about this script
this linux shell script checks, if a storj node runs into errors and alerts the operator by discord push messages as well as emails. requires at least one storj node running with docker on linux.
features
- multinode support
- optionally discord (as quick notifications) and/or mail (with error details) alerts
- alerts, in case:
- audit, suspension and/or online scores are below a threshold (storj node disqualification risk)
- audit timeouts are recognized (pending audits; discqualification risk)
- audit time lags: download started vs. download finished is larger than 3 mins (storj node disqualification risk)
- a threshold of repair gets/puts and downloads/uploads are reached (storj node disqualification risk)
- there was no get/put at all in the last hour (storj node disqualification risk)
- any other fatal error occurs, incl. issues with docker stability
- storj node version is outdated
- the node is offline (docker container not started)
- reports:
- disk usage
- success rates audits, downloads, uploads, repair up-/downloads
- estimated payouts for today and current month
- todays upload and download statistics
- optimized for crontab and command line usage
- supports redirected logs to a file
- only requires curl, jq, bc and (optionally) swaks to run
optimzed / tested for
(dependencies
- storj node node up and running, within a
- docker container
- curl (http requests)
- jq 1.6 (JSON parsing)
- bc (arbitrary precision calculator)
- swaks (mail sending, smtp)
- discord.sh (discord pushes)
setting up storj system health
- optional: setup a webhook in the desired discord text channel
- optional: grab your smtp email authentication data
- download (or clone) a copy of
discord.sh* - download (or clone) a copy of
storj-system-health.shandstorj-system-health.credo** - optional: setup discord and mail variables in
storj-system-health.credo - Go nuts
* wget https://raw.githubusercontent.com/ChaoticWeg/discord.sh/master/discord.sh
** wget https://raw.githubusercontent.com/dusselmann/storj-system-health.sh/main/storj-system-health.sh && wget https://raw.githubusercontent.com/dusselmann/storj-system-health.sh/main/storj-system-health.credo
setting up variables in *.credo
you will need to modify these variables in *.credo for your specific node and smtp mail server configuration. the *.credo file must not include comments and blank lines, the following description is just for your explanation:
## discord settings
DISCORDON=true. # enables (true) or disables (false) discord pushes
DISCORDURL=https://discord.com/api/webhooks/...
# your discord webhook url
## mail settings
MAILON=true # enables (true) or disables (false) email messages
MAILFROM="" # your "from:" mail address
MAILTO="" # your "to:" mail address
MAILSERVER="" # your smtp server address
MAILUSER="" # your user name from smtp server
MAILPASS="" # your password from smtp server
## alerting settings
SATPINGFREQ=3600 # in case satellite scores are below threshold,
# value in seconds, when next alert will be sent earliest
## storj node docker names and urls
NODES=storagenode # storage node names, multiple: separated with comma,
# e.g. storagenode,storagenode-a,storagenode-b
NODEURLS=localhost:14002
# storage node dashboard urls, multiple: separated with comma,
# e.g. localhost:14002,192.168.171.5:14002
## node data mount points
MOUNTPOINTS=/mnt/node # your storage node mount point, multiple: separated with comma
# e.g. /mnt/node,/mnt/node-a,/mnt/node-b
# enter 'source' from the docker run command here
## specify redirected logs per node
NODELOGPATHS=/ # put your relative path + log file name here,
# in case you've redirected your docker logs with
# e.g. config.yaml: 'log.output: "/app/config/node.log"'
# / -> for non-redirected logs
# /node.log -> for single node redirect
# /,/ -> for 2 node with non-redirected logs
# /node1.log,/node2.log -> for 2 nodes with redirects
# /node.log,/ -> only 1st is redirected
# /mnt/hdd1/node.log -> full path possible, too
## log selection specifica - in alignment with cronjob settings
LOGMIN=60 # latest log horizon to have a detailled view on, in minutes
# -> change this, if your cronjob runs more often than 60m
LOGMAX=720 # larger log horizon for overall statistics, in minutes
make sure, your script is executable by running the following command. add ‘sudo’ at the beginning, if admin privileges are required.
chmod u+x storj-system-health.sh # or:
sudo chmod u+x storj-system-health.sh
chmod u+x discord.sh # or:
sudo chmod u+x discord.sh
usage
you can run the script in debug mode to force a push message to your discord channel (if enabled) although no error was found - or without the debug flag to run it in silent mode via crontab (see automation chapter).
./storj-system-health.sh -d # for a regular discord push message or:
./storj-system-health.sh # for silent mode
optionally you can pass another path to *.credo, in case it has another name or source:
./storj-system-health.sh -c /home/pi/anothername.credo
in order to use the estimated payout information, which looks like so:
message: [sn1] : hdd 38.62% > OK 0.25$ / 11.77$
… you should set your crontab to be run around 23:55 UTC. You need to adjust the timing, if you have a couple of nodes and/or huge log files to be analysed: the script needs to be finished before the next full hour, ideally latest 23:59:59 UTC.
it also supports a help command for further details:
./storj-system-health.sh -h
automation with crontab
to let the health check run automatically, here’s a crontab example for linux, which runs the script each hour.
15,35,55 * * * * pi /home/pi/storj-system-health.sh -d > /dev/null
for macos please be aware of the following specifics:
- use
crontab -eandcrontab -l, although it is depricated (for now it works) - you do not have to use the user name, it’s to be executed with the current user
- use full paths to your script and credo file
- find out your standard path with
echo §PATHand set it in crontab
SHELL=/bin/sh
PATH="/opt/homebrew/opt/sqlite/bin:/opt/homebrew/bin:/opt/homebrew/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin"
# UNIX:
58 * * * * pi cd /home/pi/scripts/ && ./storj-system-health.sh -ev
10 7,19 * * * pi cd /home/pi/scripts/ && ./storj-system-health.sh -ed
# MACOS
# 58 * * * * /Users/me/storj-system-health.sh -ev >> /Users/me/Desktop/checks.txt 2>&1
# 10 7,19 * * * /Users/me/storj-system-health.sh -ed -c /Users/me/my.credo >> /Users/me/Desktop/checks.txt 2>&1
