It send notification using 5 | [Gotify](https://gotify.net) with cURL. 6 | 7 | In scripts whose names are singular, 8 | don't forget to update thoses variables : 9 | 10 | * `GOTIFY_URL` (unnecessary if using configuration file : see below) 11 | * `GOTIFY_TOKEN` (unnecessary if using configuration file : see below) 12 | 13 | I run those scripts with scheduled tasks on my 14 | Synology NAS. This is why you can see some weird stuff 15 | like `export LANG=en_US.UTF-8` (to send emojis correctly) 16 | and the path `/volume1` 17 | Since it's in Bash, it should work on Linux (tested also on Ubuntu). 18 | 19 | In my implementation, I run `backups.sh` one day of the week 20 | and `snapshots.sh` the next day. 21 | 22 | Further explanation 23 | [here](https://www.scrample.xyz/sauvegarde-avec-rsync/) 24 | (but in french) with the original Telegram based notifications scripts. 25 | 26 | 27 | ### Configuration file (optional) 28 | 29 | Copy `gotify-notify.conf` to the `/etc/` folder or be lazy : 30 | ``` 31 | wget https://raw.githubusercontent.com/anup92k/scripts/master/backups/gotify-notify.conf -O /etc/gotify-notify.conf 32 | ``` 33 | 34 | Don't forget to update it with your personnal credentials ! 35 | 36 | 37 | ### Rsync 38 | 39 | The `backup.sh` script is called trough `backups.sh`. 40 | Every backups result in a text log file which need to be kept 41 | in order to do the snapshot. 42 | 43 | 44 | ### Snapshot 45 | 46 | Making a snapshot is implemented by just doing a 47 | tarball of the "rsynced" folder. 48 | 49 | The `snapshot.sh` script is called trough `snapshots.sh`. 50 | 51 | *This script also remove Snapshots which are more than 90 days old.* -------------------------------------------------------------------------------- /backups/backup.sh: -------------------------------------------------------------------------------- 1 | #!/bin/bash 2 | export LANG=en_US.UTF-8 3 | 4 | # Gotify parameters 5 | GOTIFY_URL="https://gotify.blablabla.mu" 6 | GOTIFY_TOKEN="Az3rTy" # Your token here 7 | 8 | # Configuration file 9 | FILE_CONF="/etc/gotify-notify.conf" 10 | 11 | # Handling configuration file (if present) 12 | if [[ -f "${FILE_CONF}" ]]; then 13 | GOTIFY_URL=$(grep "server-url=" $FILE_CONF | cut -d'=' -f2) 14 | GOTIFY_TOKEN=$(grep "access-token=" $FILE_CONF | cut -d'=' -f2) 15 | fi 16 | 17 | # Handling options 18 | while getopts "S:H:b:d:h" option 19 | do 20 | case $option in 21 | S) 22 | serverName=$OPTARG 23 | ;; 24 | H) 25 | serverIP=$OPTARG 26 | ;; 27 | b) 28 | backupStorage=$OPTARG 29 | ;; 30 | d) 31 | serverDirectory=$OPTARG 32 | ;; 33 | h) 34 | echo "Usage :" 35 | echo -n "$(basename $0) " 36 | echo -n "-S [Server Name] " 37 | echo -n "-H [Hostname or IP address] " 38 | echo -n "-b [Backup Storage] " 39 | echo -n "-d [Directories to Save] " 40 | echo "" 41 | exit 0 42 | ;; 43 | :) 44 | echo "Argument needed for $OPTARG" 45 | exit 2 46 | ;; 47 | \?) 48 | echo "$OPTARG : invalid option" 49 | exit 3 50 | ;; 51 | esac 52 | done 53 | 54 | # Testing correct number of argument 55 | if [ $# -ne 8 ]; then 56 | echo "Not right number of argument" 57 | echo "Use option '-h' for help" 58 | exit 1 59 | fi 60 | 61 | # Gotify Checks 62 | ## Do you have cURL ? 63 | if [[ $(command -v curl >/dev/null 2>&1) ]]; then 64 | echo "FATAL ERROR: This script require cURL !" 65 | exit 2 66 | fi 67 | # Test Gotify server connexion (health check) 68 | curlHttpResult=$(curl "${GOTIFY_URL}/health?token=${GOTIFY_TOKEN}" --output /dev/null --silent --write-out %{http_code}) 69 | if [[ $? -ne 0 ]]; then 70 | echo "FATAL ERROR: cURL health check command failed !" 71 | exit 3 72 | fi 73 | # Check HTTP return code ("200" is OK) 74 | if [[ $curlHttpResult -ne 200 ]]; then 75 | echo -e "FATAL ERROR: API call failed !

75 | 76 | `error.txt` file will contain paths of non found images. 77 | `failed.txt` file will contain a list of non converted file. 78 | `toberemove.txt` file will contain the list of the removed images. 79 | Keep in mind that thoses files are cleared on every run. 80 | -------------------------------------------------------------------------------- /gohugo-cwebp/hugowebpconvert.sh: -------------------------------------------------------------------------------- 1 | #!/bin/bash 2 | 3 | # Created by : Anup92k 4 | # Date (YYYY-MM-DD) : 2021-05-04 5 | # Last update : 2021-05-04 6 | 7 | # Purpose : 8 | ## Convert images used in Hugo posts 9 | ## into WebP format and update thoses contents 10 | 11 | # Hugo root path (where `content` and `static` are) 12 | HUGO_ROOT="/my/root/path/to/hugo" 13 | 14 | # Conversion parameters 15 | CONVERT_PARAM="-m 6 -mt -quiet" 16 | 17 | # Not using temp file because keeping them 18 | # should be usefull 19 | true > failed.txt 20 | true > error.txt 21 | true > toberemove.txt 22 | 23 | while read line 24 | do 25 | POST="${HUGO_ROOT}/$(echo $line | awk '{print $1}')" 26 | IMG="${HUGO_ROOT}/static$(echo $line | awk '{print $2}')" 27 | IMG_POST_LINK="$(echo $line | awk '{print $2}')" 28 | 29 | # Test if post really exist 30 | if [[ (-f "${POST}") ]]; then 31 | echo "ok" > /dev/null 32 | 33 | IMG_WEBP="${IMG%.*}.webp" 34 | 35 | # If webp file does not already exist 36 | # (case of same images used multiple time) 37 | if [[ !

Critical level 14 | 15 | This can be difficult to understand so look at the exemples below. 16 | 17 | ### Exemples 18 | 19 | So, my `sensors` result look like this : 20 | 21 | ``` 22 | coretemp-isa-0000 23 | Adapter: ISA adapter 24 | Package id 0: +51.0°C (high = +100.0°C, crit = +100.0°C) 25 | Core 0: +47.0°C (high = +100.0°C, crit = +100.0°C) 26 | Core 4: +47.0°C (high = +100.0°C, crit = +100.0°C) 27 | Core 8: +49.0°C (high = +100.0°C, crit = +100.0°C) 28 | Core 12: +47.0°C (high = +100.0°C, crit = +100.0°C) 29 | Core 16: +49.0°C (high = +100.0°C, crit = +100.0°C) 30 | Core 20: +48.0°C (high = +100.0°C, crit = +100.0°C) 31 | Core 28: +50.0°C (high = +100.0°C, crit = +100.0°C) 32 | Core 29: +50.0°C (high = +100.0°C, crit = +100.0°C) 33 | Core 30: +50.0°C (high = +100.0°C, crit = +100.0°C) 34 | Core 31: +50.0°C (high = +100.0°C, crit = +100.0°C) 35 | 36 | acpitz-acpi-0 37 | Adapter: ACPI interface 38 | temp1: +27.8°C 39 | 40 | mt7921_phy0-pci-0400 41 | Adapter: PCI adapter 42 | temp1: +48.0°C 43 | 44 | nvme-pci-0100 45 | Adapter: PCI adapter 46 | Composite: +43.9°C (low = -0.1°C, high = +76.8°C) 47 | (crit = +78.8°C) 48 | ``` 49 | 50 | First, I want the "Package id 0" sensor value. 51 | So my line filter is gonna be `Package`. 52 | As this value is only present one time in the output, the second argument is `1`. 53 | The temperature value is the fourth value of the line (`4`). 54 | I want the warning value to be `60` and `80` for the critical value. 55 | 56 | So, for this sensor, the command will be : 57 | 58 | ```bash 59 | ./my_check_sensors.sh Package 1 4 60 80 60 | ``` 61 | 62 | I also want the motherboard sensors (mt7921_phy0-pci-0400) but the only 63 | filter available is `temp1` wich is present on two lines. 64 | By putting the second argument value to 2, the script will get `temp1` second value ! 65 | 66 | So, for this sensor, the command will be : 67 | 68 | ```bash 69 | ./my_check_sensors.sh temp1 2 2 60 80 70 | ``` 71 | 72 | ### Limitations 73 | 74 | - Value is treated as Celsius 75 | - `sensors` is not tested 76 | -------------------------------------------------------------------------------- /nagios-plugins/check_sensors/my_check_sensors.sh: -------------------------------------------------------------------------------- 1 | #!/bin/bash 2 | 3 | #
