+# External Check Zabbix
+
+This is a brief guide on setting up external checks in Zabbix.
+You can find example scripts in this folder.
+
+## Preparation
+
+1. Make sure your script is in
+
+```C
+/usr/lib/zabbix/externalscripts
+```
+
+> The default location can be changed in `/etc/zabbix/zabbix_server.conf`
+> by editing `ExternalScripts=/usr/lib/zabbix/externalscripts`
+
+**Ensure that you have only one tab open when creating anything in Zabbix (items/triggers/hosts).**
+
+> It's likely that the last used tab is overwriting session data.
+
+## Create the item in Zabbix
+
+> Item is a tool that gathers data from device, system or external script
+
+1. Navigate to **Configuration** > **Hosts**.
+1. Go to the **Items** next to the host you want to monitor.
+1. Click **Create item** in top right.
+- Change Type to **External check**.
+- As key use your script name together with desired **Macro**, for example `script.sh[{HOST.IP}]`.
+
+> [External Checks](https://www.zabbix.com/documentation/current/en/manual/config/items/itemtypes/external)
+> [List of macros](https://www.zabbix.com/documentation/current/en/manual/appendix/macros/supported_by_location#host-inventory)
+
+## Create the trigger
+
+> Trigger is a rule that watches for specific events, like high CPU usage.
+
+1. Navigate to **Configuration** > **Hosts**.
+1. Go to the **Triggers** next to the host with the item you want to monitor.
+1. Click **Create trigger** in top right.
+- Severity: Select as needed.
+- Expression: press Add
+    + Item: Select the item for which you want to create a trigger.
+    + Function: Defines how your trigger will be activated.
+    + Result: Actual rule of activation.
+
+## Testing
+
+1. Test manually.
+- login as **zabbix** user and go to the script location.
+- run your script as zabbix.
+
+1. Test in zabbix web interface.
+- Go to your item location.
+- If you are using external checks, **Test** option should be available.
+- Check if you Macros give proper data to your script.
+- Press **Get value and test**.
+
+1. Common problems.
+- Timeout: you can change Timeout value in `/etc/zabbix/zabbix_server.conf`
+- Make sure all necesery files and commands are accessible for zabbix user.
+- If you find something else, please update the file.
+
+## Templates
+
+1. Navigate to **Configuration** > **Templates**.
+1. Click **Create template** in top right.
+- Specify the name, group and other information if needed.
+1. Add **items**, **trigger** and **macros** if needed.
+1. Link the template to **Hosts**
+1. Mass update
+- Go to **Hosts**.
+- Check the boxes next to the desired hosts.
+- Scroll to the bottom and click **Mass update**.
+    + Select **Link templates**.
+    + Choose **Link**.
+    + Enter your template name.
+    + Press **Update**.
+
+1. Single update
+- Go to **Hosts**.
+    + Open desired **Host**.
+    + Add your Template under Templates.
+    + Press **Update**.

+# How To implement This script?
+
+1. Move `flash_probe.sh`, `flash_read.sh`, `flash_write.sh` to external script location.
+
+- By default it is:
+
+```C
+/usr/lib/zabbix/externalscripts
+```
+
+2. Create Crontab job.
+
+```C
+crontab -e
+```
+
+```C
+crontab -e
+```
+
+> The script runs every 30 minutes between 4:00 AM and 10:00 PM, Monday to Friday.
+
+```C
+*/30 4-22 * * 1-5 /usr/lib/zabbix/externalscripts/flash_probe.sh
+```
+
+## Create Template
+
+1. Navigate to **Configuration** > **Templates**.
+2. Click **Create template** in top right.
+- Specify the name, group and other information if needed.
+
+## Create Items
+
+1. First item.
+- Change type to **External check**.
+- Set Key to `flash_read.sh[{HOST.IP}]`.
+- Set update interval to 5m.
+
+2. Second item.
+- Change type to **External check**.
+- Set Key to `flash_write.sh[{HOST.IP}]`.
+- Set **update interval** to **5m**.
+
+## Create Triggers
+
+1. First trigger.
+- Severity: **High**
+- Name: Clip Fail
+- Expression:
+
+```C
+min(/Flash probe/flash_read_2zabbix.sh[{HOST.IP}],15m)=2 and
+last(/Flash probe/flash_read_2zabbix.sh[{HOST.IP}])=2
+```
+
+2. Second trigger.
+- Severity: **Information**
+- Name: Platform checked out
+- Expression:
+
+```C
+max(/Flash probe/flash_read_2zabbix.sh[{HOST.IP}],15m)=1 and
+min(/Flash probe/flash_read_2zabbix.sh[{HOST.IP}],15m)=1 and
+last(/Flash probe/flash_read_2zabbix.sh[{HOST.IP}])=1
+```
+
+## Link Hosts to the template
+
+1. Mass update
+- Go to **Hosts**.
+- Check the boxes next to the desired hosts.
+- Scroll to the bottom and click **Mass update**.
+    + Select **Link templates**.
+    + Choose **Link**.
+    + Enter your template name.
+    + Press **Update**.
+
+2. Single update.
+- Go to **Hosts**.
+    + Open desired **Host**.
+    + Add your Template under Templates.
+    + Press **Update**.
+
+## Testing
+
+1. Test manually.
+- login as **zabbix** user and go to the script location.
+- run your script as zabbix.
+
+> You can incorporate Zabbix macros into your command, `./script.sh '192.168.10.0'`.
+
+2. Test in zabbix web interface.
+- Go to your item location.
+- If you are using external checks, **Test** option should be available.
+- Check if you Macros give proper data to your script.
+- Press **Get value and test**.
