Pure computed observables purely computed monitoring propertiesThe Pure Computational monitoring attribute is introduced in knockout3.2.0, which provides a better choice of speed and memory performance for conventional computational monitoring properties in most cases. This
Pure computational monitoring, available in knockout 3.2.0, provides better management of performance and memory. This is because pure compute monitoring does not contain subscriptions that depend on him. Features include:
Prevent memory leaks
Reduced computational overhead: The value is no longer observed
Pure computed observablesThe Pure computed observables is launched by KO in version 3.2.0. She has a lot of improvements over previous computedobservables:
Prevent memory leaks
Reduce computational overhead
In the purecomputed function, switch between the two states as the relevant monitoring attribute values change.

Dual-machine hot with two implementation modes, one is based on shared storage devices, the other is not shared storage devices, generally referred to as a pure software approach.
Dual-Machine hot standby based on storage sharing is the most standard scheme for dual-machine hot standby.
For this approach, two servers
This article mainly introduces the functions of pure js to implement local storage with an infinite space size. The source code and demo are all provided to you. This article focuses on the implementation principles. The specific practices can be freely used by our partners. I haven't written a blog for a long time. I thought that I didn't release the source code that I promised two years ago. Recently, I a

Bolt is a pure Go Key/value database inspired by Howard Chu's LMDB project. The goal of this project is to provide a simple, fast and reliable database for projects that do not require a full database server (such as Postgres or MySQL).
Since Bolt is used as such a low-level function, simplicity is key. The API will be small, focusing only on getting values and sett
According to imsresearch statistics, the global shipments of cameras reached 2011 in 26.46 million, and it is estimated that by 2015, the number of cameras will reach 54.54 million. For video surveillance videos alone, the daily data volume reaches thousands of petabytes, and the accumulated historical data will be larger. Driven by the large network and high-definition video surveillance systems, the video monitoring business has entered the data blo
This article explains the Zabbix monitoring of Dell Compellent storage devices through the SNMP protocol.The monitoring of the idea and monitoring network equipment is the same: first determine whether the device supports SNMP protocol, if supported, the next step to get the device's private MIB library, usually to the
The video monitoring system consists of the following components:
No.
Module name
Functions and remarks
1
Device proxy
The system communicates with the front-end device.
2
Alarm
Receive/Store alarm information (external alarm)
3
Streaming Media
Forward video streams. Due to limited concurrent connections, multiple NICs are usually configured.
4
Device Access
The front-end devic
Abstract: A video stream compression Solution Using Xvid for AVI file storage is proposed and implemented. The network video monitoring server uses Xvid to encode the collected video images, the storage system stores compressed video streams in the general AVI file format for retrieval and query.
Key words: Avi; Xvid video codecs; video
take a step-by-step way to get the value of this row.1) Show all of them first, then we'll pass the pipe to the next command to handle2) We use the grep command to get what we want.3) by awk command we get to the fourth column and then print it, $ followed by the column we want to print, print is used in conjunction with AWK, Linux print is not used alone4) After the cut this command using M to cut the score, you can get the value we wantWe're just going to show you how to get the value we want

Prometheus in the realm of container clouds, there is no doubt that more and more cloud-native components directly provide Prometheus metrics interfaces without additional exporter. Therefore, the use of Prometheus as the whole cluster monitoring program is appropriate. But metrics stores this block, Prometheus provides local s
