  1. Scaling the Firehose API and Consumers If you’re still losing logs even though you’ve correctly scaled Dopplers, you probably need to scale your Firehose API and consumers. Categories:   CF    Cloud Foundry    PAS    Pivotal Application Service    Loggregator    Logging & Metrics   
  2. Scaling Doppler VMs in Cloud Foundry When your Cloud Foundry logging system is not working optimally, one of the reasons could be improperly scaled Doppler VMs. Read this learn if this is the case and get general guidelines for how to properly scale your Doppler VMs. Categories:   CF    Cloud Foundry    PAS    Pivotal Application Service    Loggregator    Logging & Metrics   
  3. A High-performing Mid-range NAS Server, Part 3: 10 GbE Upgrading our iSCSI (Internet Small Computer System Interface) NAS (network-attached storage) server from 1 GbE (gigabit ethernet) to 10 GbE increased our vSphere VM’s (Virtual Machine’s) sequential read throughput 43%, sequential write throughput 940% (!), and IOPS (Input/Output Operations Per Second) 60%. Categories:   Logging & Metrics    FreeNAS   
  4. Benchmarking the Disk Speed of IaaSes It’s helpful to know the performance characteristics when selecting a disk type for an Infrastructure as a Service (IaaS). In this blog post we describe the results of benchmarking various disk types of various IaaSes, including Amazon Web Services (AWS), Microsoft Azure, Google Compute Engine (GCE), and VMware vSphere. We measure Input/output operations per second (IOPS), read throughput, and write throughput. Categories:   BOSH    Logging & Metrics
