Hardware Recommendations

Standard

The following is hardware recommendation for up to 3 concurrent users, and < 10 GB of daily logs volume:

  • 4 CPU cores (2.5-3 GHz per core)
  • Standard Linux or Windows 64-bit or 32-bit distribution 
  • 8 GB RAM

The following is hardware recommendation for up to 5 concurrent users, and < 10 GB of daily logs volume:

  • 8 CPU cores (3 GHz per core)
  • Standard Linux or Windows 64-bit OS
  • 16 GB RAM

 

Cluster

The following is hardware recommendation for up to 25 concurrent users, and higher daily logs volume:
(contact support@xpolog.com to determine if a cluster is needed. More information about clustering can be found here. See installations details at XpoLog Cluster Installation)

  •   Processor node
    •  <25 GB/day (minimum): 4 CPU cores, 8 GB memory, 64-bit OS
    • <100 GB/day: 8 CPU cores, 16 GB memory, 64-bit OS
    • <500 GB/day: 16 CPU cores, 16 GB memory, 64-bit OS
  • UI node
    • <25 GB/day (minimum): 4 CPU cores, 8 GB memory, 64-bit OS
    • <100 GB/day: 4 CPU cores, 16 GB memory, 64-bit OS
    • <500 GB/day: 8 CPU cores, 16 GB memory, 64-bit OS

Storage

XpoLog collection, index and search operations benefit from a disk subsystem that is designed to the system's needs.

Capacity: Generally, the total required storage is calculated based on [DAILY AVERAGE LOG] x [RETENTION POLICY] x 1/2
The required storage for standard application logs may be closer to 35%. It is possible to tune the indexing density to reduce the required storage down to 15%.

ArchitectureRAID 0, 10, 01, 0+1 will give the best performance, while RAID 5 will offer the worst performance.

Performance: XpoLog does many bulk reads/writes and many disk seeks. We recommend storage that provides high number (1000+) of random input/output operations per second (IOPS).

As faster the storage is, XpoLog will present better performance. XpoLog processing engines mostly perform write operations but not only, while XpoLog UI engines mostly perform read operations but not only.
It is mandatory to perform tests on your set of data and configuration deployment to determine optimized performance since it may vary between different types of data and searches XpoLog performs.

Note: In Linux/Solaris standalone installations, it is recommended to allocate a high number of open files and processes to the user that runs XpoLog.
