# Modified zabbix proxy with MSSQL support
|
|
|
|
[](https://drone.asperti.com/paspo/docker-zabbix-proxy-mssql)
|
|
|
|
## Available tags
|
|
|
|
Because of unavailability of the Microsoft ODBC driver for other architectures, only `amd64` is supported. We can easily expand that in the future.
|
|
|
|
These are the supported upstream flavours:
|
|
|
|
| flavour | image to use |
|
|
|---------|-------------------------------------------------------|
|
|
| sqlite3 | `docker.asperti.com/paspo/zabbix-proxy-sqlite3-mssql` |
|
|
| mysql | `docker.asperti.com/paspo/zabbix-proxy-mysql-mssql` |
|
|
|
|
These are the supported upstream versions:
|
|
|
|
| version |
|
|
|---------|
|
|
| 7.0 |
|
|
| 6.0 |
|
|
|
|
You can use the desired version as image tag (e.g. `docker.asperti.com/paspo/zabbix-proxy-sqlite3-mssql:7.0`), the correct arch will be used.
|
|
If you prefer, you can also pin to a specific architecture: `docker.asperti.com/paspo/zabbix-proxy-sqlite3-mssql:7.0-amd64`.
|
|
|
|
## Usage with docker compose
|
|
|
|
```yaml
|
|
version: '3.9'
|
|
|
|
services:
|
|
zabbix-proxy:
|
|
image: docker.asperti.com/paspo/zabbix-proxy-mysql-mssql:7.0
|
|
restart: always
|
|
ports:
|
|
- '10051:10051'
|
|
volumes:
|
|
- ./zabbix-proxy.psk:/var/lib/zabbix/enc/zabbix-proxy.psk:ro
|
|
- ./odbc.ini:/etc/odbc.ini:ro
|
|
environment:
|
|
ZBX_DATASENDERFREQUENCY: 20
|
|
ZBX_CONFIGFREQUENCY: 300
|
|
ZBX_STARTDISCOVERERS: 3
|
|
ZBX_TLSACCEPT: psk
|
|
ZBX_TLSCONNECT: psk
|
|
ZBX_TLSPSKFILE: zabbix-proxy.psk
|
|
ZBX_TLSPSKIDENTITY: "PSK identity"
|
|
ZBX_SERVER_HOST: zabbix.server.com:12345
|
|
ZBX_HOSTNAME: px_73271_example
|
|
```
|
|
|
|
## Create the PSK file
|
|
|
|
```sh
|
|
openssl rand -hex 32 | tee /zabbix-proxy.psk
|
|
```
|
|
|
|
## Create the odbc.ini
|
|
|
|
```ini
|
|
[server_dsn_123]
|
|
Driver = ODBC Driver 17 for SQL Server
|
|
DSN = MSSQL17
|
|
Server = tcp:192.168.12.34
|
|
Port = 1433
|
|
```
|
|
|
|
## Configuration in zabbix
|
|
|
|
First, apply the `MSSQL by ODBC` template to an host. You can find it [here](https://www.zabbix.com/integrations/mssql).
|
|
Then configure the following macros:
|
|
|
|
| Macro | Value |
|
|
|-------------------|--------------------------------------------------------------------------------------|
|
|
| {$MSSQL.DSN} | This refers to the `odbc.ini` file. `server_dsn_123` in this example. |
|
|
| {$MSSQL.INSTANCE} | If needed, you can put here the name of the instance, in the format `MSSQL$instance` |
|
|
| {$MSSQL.USER} | No need to explain. |
|
|
| {$MSSQL.PASSWORD} | Also, no need to explain. |
|
|
|
|
## Monitoring user
|
|
|
|
It's always better to use a dedicated user for monitoring. Please don't use `sa`.
|
|
|
|
```sql
|
|
USE [master];
|
|
CREATE LOGIN zbx_monitor
|
|
WITH PASSWORD=N'superSecurePassword',
|
|
DEFAULT_DATABASE=[master],
|
|
DEFAULT_LANGUAGE=[us_english],
|
|
CHECK_EXPIRATION=OFF,
|
|
CHECK_POLICY=OFF
|
|
GRANT VIEW SERVER STATE TO zbx_monitor;
|
|
GRANT VIEW ANY DEFINITION TO zbx_monitor;
|
|
USE msdb;
|
|
CREATE USER zbx_monitor FOR LOGIN zbx_monitor;
|
|
GRANT SELECT ON OBJECT::msdb.dbo.sysjobs TO zbx_monitor;
|
|
GRANT SELECT ON OBJECT::msdb.dbo.sysjobservers TO zbx_monitor;
|
|
GRANT SELECT ON OBJECT::msdb.dbo.sysjobactivity TO zbx_monitor;
|
|
GRANT EXECUTE ON OBJECT::msdb.dbo.agent_datetime TO zbx_monitor;
|
|
```
