temporary statuses and has iterative functions. First, let's take a look at their memory usage and use the generator to generate the set, dict, generator, tuple, and list of The 100000 elements. The consumed memory dict, set, list, and tuple are reduced sequentially, and the size of the generated object is the same. Because generator does not generate data tables, it does not need to consume memory: import sysfrom memory_profiler import profile@profiledef create_data(data_size): data_generat

little buddy who hasn't mastered it quickly. Typically, a similar log hint can be found in the system log when OOM occurs: The MySQL 5.7 Library Performance_schema adds the following tables for viewing memory consumption from each dimension: Memory_summary_by_account_by_event_nameMemory_summary_by_host_by_event_nameMemory_summary_by_thread_by_event_nameMemory_summary_by_user_by_event_nameMemory_summary_global_by_event_nameIn simple terms, it is possible to monitor memory based on user, host,

Because generator does not generate a data table, it does not need to consume memory: Import sysfrom Memory_profiler import profile@profiledef create_data (data_size): Data_generator = (x for x in Xrange (DA ta_size)) Data_set = {x for x in Xrange (data_size)} data_dict = {x:none for x in Xrange (data_size)} data_tuple = Tuple (x for x in Xrange (data_size)) data_list = [x for x in Xrange (data_size)] return d

. The main functions to be implemented are as follows: 1. system status, such as cpu, memory, and swap; 2. MySQL performance and running status;Others are mainly disruptive data storage and visualization. 1. Use SNMP to capture system status SNMP is indeed a very convenient protocol. It can be used to obtain almost all the information of network devices. Both Linux and Windows can be well supported. MIB is a complex database that can obtain the inf

sent (such as the total number of sent bytes, number of packets, and errors ). What we are interested in here is that they are sad that different network devices extract the total sent data and received data. The following code shows how to extract the information from the/proc/net/dev file. #!/usr/bin/env pythonfrom __future__ import print_functionfrom collections import namedtupledef netdevs(): ''' RX and TX bytes for each of the network devices ''' with open('/proc/net/dev') as f:

management workstation can also control it by writing data to the managed nodes. When a managed node generates a special event, the managed node can send a simple network event message to the management workstation. This process is called sending a trap, the management workstation and the managed node communicate through the Network Management Protocol. Basic Principles of SNMP SNMP adopts a special form of client/server model: Agent/management station model. Network management and maintenance
