This topics contains information about the performance and network bandwidth utilization of the BMC PATROL Agent 9.5.
Setup configuration
The data is in this topic is based on the following configuration:
| PATROL Agent version | 9.5 |
| BMC PATROL for VMware vSphere | 4.0 |
| Number of ESXi hosts | 79 |
| Number of virtual machines | 1825 |
| Number of PATROL instances | 33576 |
| Number of parameters | 109792 |
Assumptions
The data is in this topic is based on the following assumption:
- The PATROL Agent and BMC PATROL for VMware vSphere are installed on Microsoft Windows 2008 R2 x86.
The PATROL Agent and BMC PATROL for VMware vSphere monitor a large virtual center that comprises 1829 virtual machines.
The PATROL Agent is connected to the Integration Service and only data is sent to Infrastructure Management using the Integration Service.
The network bandwidth between the PATROL Agent and the Integration Service is monitored using tools such as NetLimiter and PerfMon when the PATROL Agent is sending only data to the Integration Service.
All the readings are taken in a network bandwidth capacity of 1 Gbps.
PATROL Agent tuning parameters
The following parameters have been documented based on testing the default configuration variables for the data flow between the PATROL Agent and the Integration Service:
| Parameter | Configuration value | Supported range |
|---|---|---|
| Default maximum event message to flow to the Integration Service in one cycle = 100 | "/AgentSetup/integration/GDD/statQueueSize" = { REPLACE = "100" } | 50 - 1000 |
| Default maximum data message to flow to the Integration Service in one cycle= 100 | "/AgentSetup/integration/GDD/dataQueueSize" = { REPLACE = "100"} | 50 - 1000 |
Taking the details in the Setup configuration table, the data value transfer rate between the PATROL Agent and the Integration Service is at 100 parameter values per second.
Scalability
The following table contains information about the network bandwidth utilized between the PATROL Agent and the Integration Service. The reading in the table is on the computer in which the PATROL Agent is installed on port 3183.
Network bandwidth usage in KB/sec | Only data |
|---|---|
| Minimum | 2.06 KB/s |
| Average | 2.73 KB/s |
| Maximum | 3.01 KB/s |
The following table contains information about the network bandwidth utilized between the Integration Service and the BMC TrueSight Infrastructure Management Server. The reading in the table is on the computer in which the Integration Service is installed on port 12124.
Network Band Width Usage in KB/sec | Only data |
|---|---|
| Minimum | 18.33 KB/s |
| Average | 19.06 KB/s |
| Maximum | 19.80 KB/s |
From the tables above:
- The average data bandwidth measurement between the PATROL Agent and the Integration Service is at 2.73 KB per second. This data contains the following load:
- Total number of virtual machines = 1825
- Total number of PATROL instances = 33576
- Total number of parameters = 109792
- The average data bandwidth measurement between the Integration Service and the Agent Controller is at 19.06 KB per second.
