cat devices.conf storwize:SURB4BASSSTG.colombo.com.pt:10.71.73.242

Hi! Try to telnet 10.71.73.242 443 from host where you run script storage_discovery.py. Looks like network unavailability storwize from your host. If you can telnet to storwize, try log in via GUI Management https://10.71.73.242 under your monitoring user.

Thanks for you quick answer, I can telnet and access to the Storage, but looks like the storage:discrovery.py is trying to connect to WBEMConnection(url='https://10.71.73.242:5989', creds=('zabbix', ...), default_namespace='root/ibm', ...) If I try to open the url https://10.71.73.242:5989 gets me an error HTTP ERROR 501.

[pavlovdo]

Yes of course, WBEM works on port 5989. Try to telnet 10.71.73.242 5989 from your monitoring host. That port must be available from monitoring host. If not, add entry to ACLs on your firewall/router.

[kaishainn]

I was able to conect to the ip and port from monitoring host. telnet 10.71.73.242 5989 Trying 10.71.73.242... Connected to 10.71.73.242. Escape character is '^]'.

[kaishainn]

This is my pystormon.conf cat pystormon.conf [NetworkDevice] device_file = /etc/zabbix/externalscripts/pystormon/devices.conf login = zabbix name_space = root/ibm password = 1234 zabbix_server = 10.71.73.49

cat devices.conf storwize:SURB4BASSSTG.colombo.com.pt:10.71.73.242

[pavlovdo]

According to https://pywbem.readthedocs.io/en/latest/client/exceptions.html#pywbem.ConnectionError, it's a network or WBEM-server (storwize) issue: "This exception indicates a problem with the connection to the WBEM server" Therefore: 1) Check your connection between monitoring host and storwize again; 2) Try to tcpdump this connection; 3) Check logs of your network devices.

[kaishainn]

I fixed and now is working. One question, which metrics can I get from the Storage with pystorm?

[pavlovdo]

How did you fix it ? With pystormon you can show status of physical disks and perfomance of volumes

If you interested in more information tell me what information you need. I will consider the possibility add these metrics in next releases.

[kaishainn]

Yes, all the scripts are working since yesterday but I´m still not seeing any info in zabbix...One question when I create the host in zabbix where I must to set the storage IP, agent,snmp, jmx, ipmi.....??

[pavlovdo]

In zabbix host configuration you have to set Host name and IP address for Agent Interface only. In zabbix host config you have to set the same hostname as in the file devices.conf: SURB4BASSSTG.colombo.com.pt Otherwise zabbix server can't find object for save item values received from python script zabbix trapper.

Great! I´m seeing the data in grafana! Thanks so much for your help and support!
