    hi im very new to observium.. i have some doubts on if observium can manage with only manageable switches like cisco.. because i couldn’t find any host in my network.. im using 192.168.1.0 range of IP. i dont have manageable switch.. i confiugred observium i can logoin.. how to find other hosts in my network..

  4. emjay says:

    I followed this tut to the “T” and everything works great except that I can’t access the server from a remote computer on the same LAN using the IP address of the server. While on the server http://localhost or http:// gets me there but from a remote computer http:// does not get me there. I can ping the address just fine.

    Any ideas?

    • Ravi Saive says:

      Yeah that’s great you’ve successfully added remote host to Observium, it would be great if you could share the docs for adding remote hosts so others can benefit from your instructions. Can you share the screeshot for the same, so it will helpful me to trace the problem.

      You must have SNMP tools installed on remote host and make sure remote and observium server can talk each other.

    Where are the logs for this…mysql is on a different IP.

    • Ravi Saive says:

      It’s fine to have such SQL errors in the SQL revisions up to 006. No need to worry about much, just continue installation…
