Field Description
System Memory Usage
The amount of RAM that is currently used broken down by usage. It is normal for
AirWave to have very little free RAM. Linux automatically allocates all free RAM as
cache and buffer. If the kernel needs additional RAM for process it will dynamically
take it from the cache and buffer.
System Disk Throughput The rate of reading and writing from and to the disk in bytes per second.
System Swap Usage
The amount of Swap memory used by AirWave. Swap is used when there is no
more free physical RAM. A large performance penalty is paid when swap is used. If
your AirWave consistently uses swap, you should consider installing additional
RAM.
System Disk IOPs The number of disk reads and writes per second.
System Disk Outstanding
I/O Requests
The average number of outstanding I/O requests (queue depth). If it's high, it means
that I/O requests (disk reads/writes) aren't being serviced as fast as they're being
asked for.
System Disk Utilization The amount of data read from the disk and written to the disk.
System CPU Utilization
The percentage of CPU that has been used by the user and the system as well as
the amount that was idle.
Process Counts by
Service
This breaks down network usage based on Web server, database, AirWave Service,
and VisualRF processes.
Average Delay Time by
Queue Type
This shows the queue time for Async logger clients and RAPIDS processing.
I/O Throughput by
Worker/by Service
Displays reads and writes for workers (AirWave services, database, VisualRF, web
server, RRD tool and AWRRD tool) and for services (AirWave, VisualRF and web
server).
CPU Utilization by
Worker/by Service
Displays reads and writes for workers (AirWave services, database, VisualRF, web
server, RRD tool and AWRRD tool) and for services (AirWave, VisualRF and web
server).
System Network Usage
All traffic in and out measured in bits per second of your primary network interface
(Eth0 being the most common).
Usage by Protocol
Displays the amount of traffic used by Telnet, HTTPS and SNMP used by your
primary network interface (Eth0 being the most common).
AMON
Displays the number of AMONpacket traffic used by your network over the last two
hours, day, week, month, and year.
SNMPTraps
Displays the number of SNMP Trap packets in your network over the last two hours,
day, week, month, and year
Legacy SNMP Fetcher
Requests
The number of SNMP get and walk requests per second performed by the legacy
(v1 and v3) SNMP fetcher.
Legacy SNMP Fetcher
Responses
The number of SNMP OIDs received per second performed by the legacy (v1 and
v3) SNMP fetcher.
