Description: All servers in the company are Dell servers. Why do we do this monitoring? It is because the disk of a DB database on the line is damaged. Result of our operation and maintenance group (only I one, of course, I am personally responsible for, think about or the lack of their own technology) Not the first time to find out. So the network search Zabbix to monitor the Dell server.1. Monitoring tools are monitored using Dell's own OMSA tools,

, use NoOp) Improve Scheduler request queue:echo 4096 >/sys/block/sdx/queue/nr_requestsNote: When there are a large number of requests, the system request queue value is too high, this time need to increase the request queue value. A bit like MySQL in the Back_log or thread_cache_size parameters, is to increase the queue pool, so that some of the queue first put in, rather than let them wait outside, the queue came in to make a quick request, and so on after the request is the queue quickly proc

ArcGIS Server does not have an absolute hardware metric, but according to experience If the peak value of ArcGIS Server is 18 concurrent connections , The CPU must have at least 45 or more specrate values to meet the requirements. In this case, the server can return a data display request within 8 seconds. . Wh

As an OPS person, it is essential to understand the hardware-related information of each server and the system-related configuration. Although not difficult, but very fragmented, information concentration is not high. So do a set of centralized display of the above information "platform" (in fact, no platform, collect-organize-show only), its principle by a "monitoring machine" (so call it) run the main scr

This kind of blockage can occur even if you do not do backup. ” This may be due to a deadlock inside SQL Server, and it is recommended that you install the following patch on all nodes as soon as possible. http://support.microso

Review There is no doubt that mobile internet, social networking, large data and cloud computing have become the four major trends in IT development. Cloud computing also provides an ideal platform for the top three. Today, not only internet companies, many of the traditional industries of large and medium-sized enterprises are also building their own private cloud. This article is intended to introduce a reference architecture based on Windows Server
