How is possible to see Devices name in Cacti from HP Curve switch?
I see "invalid_host". There are no problems with Linux hosts. I add rsyslog.conf as first word current hostname. What to do with switch?

Likely you have syslog setup to attempt to resolve IP addresses to hosts. You might want to turn that off. Then, you will get IP Addresses that you will know that you don't have DNS entries for. Also, note that there have been some fixes lately for syslog. It's a good idea to upgrade.
