Automatically scheduled scanning

Every hour, Quantellium starts a process in the background that automatically scans the interfaces of all servers, switches, routers, firewalls etc in a project for problems or errors. To be included in a scan, a device must be:

  1. approachable with SNMP
  2. included in the project
  3. up-and-running for at least two hours

Detected problems or errors are reported as anomalies.

Detected problems or errors

Router, Switch, Server, Hub

  • Alignment, FCS or Symbol errors on duplex port {Port#} detected! These error types on full-duplex links are usually the result of a duplex or speed mismatch, bad hardware (NIC, cable or port) or a connected device generating frames with bad FCS.
  • Single or Multi Collisions on duplex port {Port#} detected! Collisions on a duplex port should not occur!
  • Late collisions on half-duplex port {Port#} detected! These kinds of errors are a result of incorrect cabling or a non-compliant number of hubs in the network. Bad NICs can also cause late collisions.
  • Late collisions on full-duplex port {Port#} detected! Should not occur!
  • Excessive collisions on half-duplex port {Port#} detected! These kinds of errors are an indication of a wiring problem, an excessively loaded network or a duplex mismatch. An excessively loaded network could be caused by having too many devices on a shared Ethernet.
  • Excessive collisions on full-duplex port {Port#} detected! Faulty NIC, cable or switch port!
  • Carrier sense errors on full-duplex port {Port#} detected! These kinds of errors on a full-duplex setting are an indication of a faulty NIC, cable or switch port!

Miscellaneous

  • The device is “up” but the primary protocol {PrimProtocol} for status monitoring does not respond. Using {SecProtocol} for the second opinion instead!
  • Status request packet loss > {LossPerc}%!
  • There’s no process named: {Process name} running on this host!
  • Application {Application name} is likely to leak memory (certainty {CertPerc}%, Reference {StartMB}, growth {GrowthMB}/day)!
