icmp monitoring

[farzin.mofarrah]

Hi experts,

I just access to Server (B) via server(A), the Zabbix Server can just monitor server (A)
how to monitor PING state of server (B) ?

Hi,
If I'm understanding this right - you want to ping Host B from Host A? In that case, if your host A is running Linux, you should be able to invoke fping and pass the result via a user parameter.
You can read more about how to define and configure user parameters here - https://www.zabbix.com/documentation...userparameters
Here's a link to a post with a similar request. this should help you with figuring out Zabbix User Parameters - https://www.zabbix.com/forum/zabbix-...-agent?t=20592

Hi,
Actually both host are running Windows, but Zabbix server has access Host A, I'm thing of a PHP script or sth like that !

You can still use User parameters to do what you need - just create a simple bat file that outputs either 1 or 0 depending on if the pinging from host A to host B succeeds or fails, point the user parameter to the file and create the corresponding item and trigger.

I just crated a batch file like this :
ping -n 1 192.168.237.62 | find "TTL" & if not errorlevel 1 set error=1 & if errorlevel 1 set error=0
and copied that to HOST A Drive c: (root)

I just added this "UserParameter=Ping_Datacenter_Servers, c:/ping.bat" to zabbix_agentd.conf

still no data back !


PS : the IP: 192.168.237.62 refers to HOST B

You may avoid the creation of user parameter using WMI. For example:
wmi.get[root\cimv2,select StatusCode from Win32_PingStatus where Address="ip" and Timeout=1000]
Item value 0 means success. This method is preferred for ping by ip, because for ping by name such item will become not supported in case of DNS problems.

Unfortunately Zabbix server can't access to Host B directly,
Actually Host A & B are in same network (192.168.x.x) and Zabbix serve just access to Host A as a NAT IP (172.27.x.x)
There is no way from Zabbix server to Host B Even with WMI Protocol

in your example there is just ONE IP address that can access via Zabbix server right ?

What do you mean by "No data"? Is there an error you're getting in Zabbix? Is the script outputting the correct value - number or text? You should try running the script and checking if the value that it's displaying is as it should be.

No data" i mean nothing will log by Zabbix, there is no error, the problem was in batch file name !!
it seems it's not allowed to make a batch file like this "ping.bat", i just renamed to "png.bat" that problem solved
but still have some other problem :

[root@localhost ~]# zabbix_get -s 172.27.0.183 -k custom.ping
zabbix_get [27812]: Get value error: ZBX_TCP_READ() failed: [104] Connection reset by peer
zabbix_get [27812]: Check access restrictions in Zabbix agent configuration


tnx.

Hi, farzin.mofarrah.
I mean windows agent's item wmi.get. The item created on the host A and has ip of the host B in the key: wmi.get[root\cimv2,select StatusCode from Win32_PingStatus where Address="192.168.x.x"]

[farzin.mofarrah]

I got this error after using wmi
/usr/lib/zabbix/externalscripts/wmi.get: [2] No such file or directory

where to get that script ?

[ArtursL]

You could try taking another look at your agent configuration in zabbix_agentd.conf - check if you have the correct server IP set there and that there are no network/firewall related restrictions regarding ports/services.
