If you plan sending data to VictoriaMetrics from multiple Prometheus instances, then add the following lines intoglobalsection ofPrometheus config: global:external_labels:datacenter:dc-123 This instructs Prometheus to adddatacenter=dc-123label to each time series sent to remote storage. The label name...
This allows application writes to be buffered in the OS layer regardless of whether the client connection has acked previous writes or not, and then the OS can optimize sending the data by parallelizing writes and/or sending larger chunks of data at a time. The benefits are clear when ...
It is a good idea to periodically monitor the CPU usage of the host. This can be done through the vSphere Client or by using esxtop or resxtop. Below we describe how to interpret esxtop data: If the load average on the first line of the esxtop CPU panel is equa...
On the other hand, East/West traffic is a form of sending and receiving data between containers deployed in the same server and can pass through multiple containers. For this type, user-space vSwitch models such as OVS-DPDK and VPP are preferred because packets are routed within the user ...
In this case we are testing one publisher and one subscriberin different processessending a 1kArray at 5Hz. This will allow us to evaluate additional overhead caused by a single pub/sub topic and detect leaks related to this activity. ...
When using a CLI to automate the instrumentation process, you can start sending telemetry data to your APM solution within minutes. Complex distributed applications use many different services, and ideally, every part of an application should be instrumented. A comprehensive APM tool provides ...
Security is an important field in the Internet of Things (IoT) systems. The IoT and security are topical domains. Because it was obtained 35,077 document results from the Scopus database. Hence, the AI (Artificial Intelligence) has proven its efficiency
The ingress throughput of the storage backend depends on the data that producers are sending directly to the broker plus the replication traffic the broker is receiving from its peers. For an aggregated throughput produced into the cluster oftclusterand a replication ...
Anytime more than one query needs to change data at the same time, the problem of concurrency control arises. For our purposes in this chapter, MySQL has to do this at two levels: the server level and the storage engine level. Concurrency control is a big topic to which a large body ...
