School Manager Performance Metrics

This article is for IT Support. 

You can use Performance Metrics to check your Linewize appliance’s operating efficiency and effectiveness. In School Manager, go to Debugging > Diagnostics > Performance Metrics.

Note

Performance metrics are only uploaded by SphireOS, which only runs on a physical Linewize appliance.

Accessing Performance Metrics

  1. Sign in to School Manager with an Owner/Global Administrator account.
  2. Select Debugging > Diagnostics > Performance Metrics.
Metric Description Use Case
appliance_gateway.connections The total number of appliance gateway connections in use over time. See if the Linewize appliance is talking to the appliance gateway successfully.
auth.radius.accounting_packets.persec The average number of radius accounting packets being processed by the appliance over time. Use to confirm if radius authentication is working as expected.
configuration.version The active configuration version on the appliance. Use to confirm the active configuration version on the appliance.
firewall.conntracker.icmp.size Number of ICMP connections tracked by the Linewize appliance over time. Identifies how many ICMP connections are being processed.
firewall.conntracker.tcp.size Number of TCP connections tracked by the Linewize appliance over time. Identifies how many TCP connections are being processed.
firewall.conntracker.total.connections Number of ICMP/TCP/UDP connections tracked by the Linewize appliance over time. Identifies the total connections being processed.
firewall.conntracker.udp.size Number of UDP connections tracked by the Linewize appliance over time. Identifies anomalies in network traffic, such as when someone floods it with UDP traffic, causing the Linewize appliance to go down.
firewall.fzagent.bypass.bytes.persec Bytes bypassed due to an agent being installed over time. Identifies the total amount of agent traffic (in Bytes) that the appliance has bypassed.
firewall.fzagent.bypass.devices.size Number of devices being bypassed by the Linewize appliance when Agent Bypass is enabled over time. Identifies how many devices are being bypassed.
firewall.fzagent.bypass.packets.persec Average number of packets bypassed per second from devices with an agent installed over time. Identifies the number of packets the appliance is bypassing that originated from a device with a Linewize agent installed.
firewall.transfer.packets.persec The total number of packets processed over time. Identifies how many packets are being processed during peak times.
firewall.transfer.persec Total bytes being forwarded by the Linewize appliance over time. Identifies the total throughput passing through the appliance.
nfqueue.filter.average_handling_time.us The average packet processing time in microseconds over time. Identifies the average time to process a packet through the Linewize appliance.
sessiondb.size The number of user sessions stored by the Linewize appliance over time. Identifies the number of unique user sessions stored on the Linewize appliance.
sysctl.net.netfilter.nf_conntrack_count The total number of conntracks in use by the Linewize appliance over time. Identifies if the Linewize appliance is approaching the conntrack maximum.
system.cpu_usage The percentage of CPU in use by the Linewize appliance over time. Identifies if the Linewize appliance is under heavy load.
system.fs.configuration.available The available space within the configuration file system on the appliance over time. Use to monitor the disk space on an appliance.
