Sizing charts and guidelines for data and event management environments

The following tables provide sizing summaries for an environment that incorporates both data collection and event management:

Provided values represent the maximum values recommended for the tested parameter.

Sizing chart for data collection of the TrueSight Infrastructure Management Server

Characteristic	Small environment	Medium environment	Large environment
Number of devices	5000	10,000	20,000
Total number of attributes	300,000	600,000	1,700,000
Total number of monitor instances on the BMC TrueSight Infrastructure Management Server	30,000	60,000	250,000
Duration of raw data retention	3 days	3 days	3 days
Duration of rate retention	3 months	3 months	3 months
Number of groups	1000	2000	3000
Number of SLOs	20	40	60

Sizing chart for event management of the TrueSight Infrastructure Management Server

Characteristic	Small environment	Medium environment	Large environment
Number of intelligent events per day ¹	10,000	20,000	40,000
Number of external events per day ¹	60,000	200,000	350,000
Number of remote cells	0	5	10
Duration of event retention²	default	default	default

^{1 Rate is based on events that are evenly distributed in a day.}
^{2 To view the default value, edit the mcell.conf file.}

Sizing chart for data collection of the Integration Service

Characteristic	Small environment	Medium environment	Large environment
Maximum number of monitor instances per Integration Service	30,000	60,000	250,000
Number of Integration Services	1	1	1
Maximum number of PATROL Agents	500	900	900

Sizing chart for multiple Integration Services running on the same Integration Service host

When multiple Integration Services are running on the same Integration Service host computer, the following sizing chart represents the data for those multiple Integration Services. Each Integration Service process requires 4 GB of memory.

Characteristic	Small environment	Medium environment	Large environment
Number of devices	5000	10,000	20,000
Total number of attributes	300,000	600,000	1,700,000
Total number of monitor instances on the BMC TrueSight Infrastructure Management Server	30,000	60,000	250,000
Duration of raw data retention	3 days	3 days	3 days
Duration of rate retention	3 months	3 months	3 months
Number of groups	1000	2000	3000
Number of SLOs	20	40	60
Maximum number of PATROL Agents that can be connected to each of the Integration Service	900	900	900

Note

When the load of the TrueSight Infrastructure Management Server is distributed among Integration Services, BMC recommends a maximum of three Integration Services instances running on a single Integration Service host computer.

Sizing chart for Infrastructure Management consoles

Characteristic	Small environment	Medium environment	Large environment
Concurrent number of users—operator console	25	50	100
Concurrent number of users—administration console	1	1	1
