First, Introduction 1) cacti is a PHP language implementation of a software, its main function is to use the SNMP service to obtain data, and then use RRDtool to store and update data, when the user needs to view the data with the RRDtool to

Cacti we also used for a long time, but its table structure has not been to care about, hollow smoked half the night time, the library table structure is probably looked under, some of the meaning of the field to share with you:Cacti data are stored

The ganglia project was initiated by the University of California and has become a widely used cluster monitoring software. Monitors and displays various status information of nodes in the cluster, such as CPU, mem, hard disk utilization, I/O load,

Nginx+tomcat is the current mainstream Java Web architecture, how to let nginx+tomcat work at the same time, can also say how to use Nginx to reverse proxy tomcat back-end equalization? The direct installation configuration is as follows: 1. JAVA

Use python to create a network card Traffic chart !!! Project Background: Using python to implement an automated network card Traffic chart, which gives us a deeper understanding of how to implement an automated O & M platform, It will also help us

　　1 grid Pyramid DefinitionPyramids can be used to improve performance. They are a reduced-sample version of the original raster dataset and can contain multiple downsampling layers. Each successive layer of the pyramid is downsampling at a scale of

For rrdtool data, write a data every 10 seconds, but the read is different from the written data. The created database is as follows: ./Bin/rrdtool create data/test. rrd -- start 1365756520 -- step 10 DS: myds: GAUGE: 100: 0: u rra: LAST: 0.5: 1:

Cacti full user manual (allowing you to use Cacti quickly and individually) I. Overview The monitoring system of Cacti and Nagios is a monitoring system that is widely used and supports a wide range of O & M personnel at home and abroad, the

To understand how rrdtool is to be used first from the RRD data storage, RRDtool is to operate the tool of the database, copy the following text to explain.0x01 What is the RRD databaseThe so-called "Round Robin" is actually a way of storing data,

I. IntroductionRRDtool refers to the Round Robin Database tool, that is, the ring Database. In terms of functionality, RRDtool can be used for data storage + data display. The well-known network traffic plotting software MRTG and Cluster Monitoring

Now want to monitor the traffic and concurrency of the service, but not so much time to write the system, the other operation and maintenance system is not familiar with, so the existing RRDtool shell made a simple monitoring interface, temporary

The first two days to the Nagios under a monitoring item to add monitoring data, found that the monitoring data is there, but later found that the graphics data is not, and suddenly do not know where the problemHere are my steps to troubleshoot the

The RRD file generated by collectD cannot be parsed directly by rrd4j. At this time, rrdtool is used to convert the RRD file into an XML file, and rrd4j converts the XML file into an RRD file that rrd4j can recognize. The figure is shown as follows.

Project background:The use of Python to achieve an automated network card flow chart drawing, which for our implementation of the automated operation and maintenance platform has a deeper understanding,will also allow us to some of the existing

Deploying Ganglia to monitor Hadoop and HBase Some performance problems often occur during Hadoop O & M. However, performance problems cannot be simply analyzed through web pages and logs. Many metrics are required. Ganglia is one of the more
