SightLine Data Collection Power Agents collect real-time performance and user-defined event data then delivers it to SightLine EDM.
SightLine collects and reports performance data for all key components of operating systems: CPU, Memory, Disk, Network and File Systems, and hundreds of other metrics including Process Information.

Network Statistics — Network statistics are collected at the controller level. SightLine collects Net Traffic Rates, Collisions (sign of network problems) and Resends (sign of controller problems), Number of Packets, Volume of Traffic, and TCP Stats, Input Packets/Sec, Output Packets/Sec, Collisions/Sec, IP Pkts Received/Sec.

NFS Statistics— Network File System (NFS) metrics provide statistics on the traffic and overhead associated with NFS operations. SightLine reports rates of Calls, Volume, and Failures to flag problems with the NFS subsystem. Client and server statistics include Calls, Badcalls, Reads, Writes, etc.

RPC Statistics — A process can be executed on a host other than the one that produces the call. Remote Procedure Calls (RPC) metrics provide information on the volume and rates of Procedure Calls to and from other hosts. SightLine reports Client and Server Statistics.

Disk Statistics — SightLine reports disk statistics provided by the kernel. Depending on the Linux platform, they can include %Busy, Volume of Traffic, Queue Length, Wait Times, and Service Times, %Read, %Write, etc.

File System— File systems can be mounted across physical disks. Their space on most Linux boxes is set and cannot be changed easily, so it is very important to monitor their use. Besides Space Utilization, SightLine reports Volume of Traffic of FS and I-nodes Used.

TTY — TTY metrics record utilization of terminal lines. SightLine reports these rates in several forms.

Memory Statistics —

Memory - These metrics include Space Utilization, Paging, and Swapping Statistics.
Swap - These metrics provide information on disk space where Paged and Swapped Memory resides. Some systems will crash if Swap Space is filled. SightLine also reports Swap Rates in blocks.
Buffer Cache - The Buffer Cache is a block of memory where I/O's are cached. This greatly enhances the performance of the disk I/O subsystem, but at the expense of available memory. SightLine reports Rates, Misses, and Hits for both Reads and Writes.

Process Level Data — The EventScope is used to view process level utilization information.
Pid# - The Process Identification Number.
Userid - The name of the User that owns this process.
Taskname - The name of the process.
Usr% (User CPU utilization) - The amount of User CPU this process used during the sample interval. On a multi-processor machine this is the value of CPU usage for this process on all CPU's.
Sys% (System CPU utilization) - The amount of System CPU this process used during the sample interval. On a multi-processor machine this is the value of CPU usage for this process on all CPU's.
Cuser% (Child user CPU utilization) - The amount of User CPU that children of this process used. You will only see values when a child of this process completes during the interval.
Csys% (Child system CPU utilization) - The amount of System CPU that children of this process used. You will only see values when a child of this process completed during the interval.
Size K (Process size) - The amount of memory that this process is using in Kilobytes.
Pri (Priority Level) - Level of Priority of the process.
Bread - The number of Block Reads done by this process during this interval.
BWrite - The number of Block Writes done by this process during this interval.
PgFlt - The number of Page Faults for this process during the interval.
