Media Flow Controller Fault Management : Stats Alarms

Stats Alarms
This section describes the stats alarms you can set. These may reach you through an email event name (configurable).
Use the stats commands to set “error” and “clear” thresholds for alarms. Table 18 shows Media Flow Controller stats alarms; all defaults are configurable. For details on stats chds (computed historic datapoints) and stats samples, see stats in the Chapter 7, “Media Flow Controller CLI Commands.”
For configuration details, see “Configuring Log Statistics Thresholds” on page 98.
1.
show stats [alarm | chd | sample]
2.
show stats [alarm <alarm_ID>] [chd <chd_ID>] [sample <sample_ID>]
3.
stats alarm <alarm_ID> enable
4.
Set rising and falling error-thresholds and clear-thresholds, as appropriate. Some alarms operate on a “rising” basis: that is, the alarm is triggered when something rises above the error-threshold and is cleared when it falls back to the clear-threshold. Other alarms operate on a “falling” basis: the alarm is triggered when something falls below the error-threshold and is cleared when it rises back to the clear-threshold.
stats alarm <alarm_ID> rising error-threshold <threshold>
stats alarm <alarm_ID> falling clear-threshold <threshold>
stats alarm <alarm_ID> falling error-threshold <threshold>
stats alarm <alarm_ID> rising clear-threshold <threshold>
5.
Export statistics to csv (comma-separated value) file; the only format supported for Release 2.0.2. The dataset to be exported is determined by the specified report name (given below). If a filename is specified, the stats are exported to a file of that name; otherwise a name is given that contains the report name and time and date of the export. Either one, both, or neither of the after and before parameters may be specified, placing boundaries on the timestamps of the instances to be exported; they may come in either order relative to each other. Use show files stats to see the file. Use file stats <filename> upload <URL> to another system.
stats export csv <report_name> [filename <filename>] [after <date> <time>] [before <date> <time>]
Example:
test-vos (config) # stats export csv cpu_util
test-vos (config) # show files stats
cpu_util-20090401-161206.csv
test-vos (config) # file stats upload cpu_util-20090401-161206.csv scp://joe@sv01/home/joe

(unless otherwise noted, default rising error threshold is 200000000 Bps; rising clear threshold is 100000000 Bps)
Disk I/O (input/output) in kilobytes per second.* Default rising error threshold is 5120 kilobytes per sec; default rising clear threshold is 4608 kilobytes per sec.
Average CPU utilization. Note that units for this alarm are hundredths of a point of the one-minute load average. For example, setting it to 100 causes an alarm if the one-minute load average is ever over 1.0 when it is sampled.
Default rising error threshold is 90%; rising clear threshold is 70%.
Paging activity (page faults). Note that units for this alarm are number of pages read from, or written to, the swap partition. The alarm is on the amount of paging activity that has occurred over the past 20 seconds. Default rising error threshold is 2000 page faults; rising clear threshold is 1000 page faults.
Percent free filesystem space. Default falling error threshold is 7% of disk space free; falling clear threshold is 10% of disk space free.
Percent of physical memory in current in use.* Default rising error threshold is 90% of physical memory used; rising clear threshold is 87%.
Network utilization (in B/ps).* Default rising error threshold is 10485760 bytes per sec; rising clear threshold is 9437184 bytes per sec.
Incoming connections per second, arrived by summing up all accepted connections and dividing by system up time. Default rising error threshold is 20000 per sec; rising clear threshold is 10000 per sec.
Number of HTTP transactions (GET requests) per second; (number of GET requests received so far divided by system up time). Default rising error threshold is 40000 per sec; rising clear threshold is 20000 per sec.
