System Load Aver-
age
The System Load average is the number of jobs currently waiting to be processed. Load is a rough metric
that will tell you how busy a server is. A typical AWMS load is around 3. A constant load of 5 to 7 is cause
for concern. A load above 10 is a serious issue and will probably result in AWMS becoming unusable. To
lower the load average try increasing a few polling periods. Increasing the polling period for APs, routers/
switches, WLSE, ACS, and so on, will decrease the amount of work AWMS needs to perform and lower the
load average. If you have a load that is consistently below 3 you might consider shortening your polling
period and observing.
NOTE: If the load is less than one the y scale will be 1 to 1000 m standing for milliseconds or
1/1000ths of 1.
System Memory
Usage
The amount of RAM that is currently used broken down by usage. It is normal for AWMS 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
Utilization
The amount of data read from the disk and written to the disk.
Swap Usage
The amount of Swap memory used by AWMS. Swap is used when the there is no more free physical RAM.
A large performance penalty is paid when swap is used. If an AWMS consistently uses swap you should
consider installing additional RAM for the box.
System CPU Usage
The percentage of CPU that has been used by the user and the system as well as the amount that was idle.
Application CPU
Usage
CPU usage broken down by application. AWMS services includes all AWMS processes except the
database and the webserver.
I/O Throughput
Displays reads and writes for workers (AMP services, database, VisualRF, web server, RRD tool and
AWRRD tool) and for services (AMP, VisualRF and web server).
CPU Utilization
Displays reads and writes for workers (AMPservices, database, VisualRF, web server, RRD tool and
AWRRD tool) and for services (AMP, VisualRF and web server).
System Network
Bandwidth (Eth0)
All traffic in and out of Eth0 measured in bits per second.
Bandwidth by
Protocol (Eth0)
Displays the amount of traffic used by Telnet, HTTPS and SNMP on Eth0.
Legacy SNMP
Fetcher (SNMP Get/
walk Requests)
The number of SNMP get and walk requests per second performed by the legacy (v1 and v3) SNMP
fetcher.
Legacy SNMP
Fetcher (SNMP
OIDs Received)
The number of SNMP OIDs received per second performed by the legacy (v1 and v3) SNMP fetcher.
High Performance
SNMP Fetcher
(SNMP Get/walk
Requests)
The number of SNMP get and walk requests per second performed by the high performance SNMP (v2c)
fetcher.
High Performance
SNMP Fetcher
(SNMP OIDs
Received)
The number of SNMP OIDs received per second performed by the high performance SNMP (v2c) fetcher.
Top 5 Tables (by
row count)
The five largest tables in AWMS. Degraded performance has been noticed for in some cases for tables
over 200,000 rows. Aruba recommends decreasing the length of time client data is stored on the AWMS
page if a user/client table exceeds 250,000 rows.
Database Table
Scans
The number of Database table scans performed by the database.
Database Row
Activity
The number of insertions, deletions and updates performed to the database.
