The places where hits (execution times) and time values are high are places where there is more room for optimization.
Memoryprofiler
Similar to "Lineprofiler" for modules based on the row parser memory usage. GitHub Address: https://github.com/fabianp/me .... PS: Install Psutil, will analyze faster.
Same as the code in "Lineprofiler" above, run the python-m memory_profiler profile.py command produces the following results:

My problems:
Recently, cacti is used to monitor a Huawei s5720 switch. The monitoring module is a template of a lower version, so a switch of a higher version cannot obtain data.
Find the cause based on the principle:
Because SNMP-based monitoring is used, the oId (Object descriptor) must be obtained for obtaining data using SNMP ). The most accurate way to obtain the oId is to contact the device manufacturer. The s5720 oid is obtained by I contact the vendor for your reference.

Send Cisco commands via SNMPAn article by Fabio Semperboni Tutorial inShare136 Tweet
In the article "How to save configurations using SNMP", I has explained how to get the Cisco configuration using SNMP. Now, I explain how to send commands via SNMP using the "Ciscoconfigcopymib" MIB; With this MIB, you can replace Running/startup configuration, send commands, save The "show" Output or reload the devic
Zabbix monitoring firewalls and switches are transmitted through the SNMP protocol for data and data analysis, which I will explain below with the Dell Firewall SonicWALL 3400 series and switch N4032. Since the Zabbix server is already installed, it is now only possible to install the SNMP protocol on the fire switch on the firewall and send the data as a client.(i) Monitoring firewallsFirst, log in to the firewall and locate the firewall's monitoring port. The port steps for this series are: Ne

There is also a friendly connection, especially the snmplink website, where you will find a lot of things.Third, you must have programming skills for engineering purposes (this is something I lack and it costs a lot)

SNMP is the abbreviation of "Simple Network Management Protocol" in English, and the Chinese meaning is "Easy network Management Protocol". SNMP is currently the most commonly used environmental management protocol. SNMP is designed to be protocol-independent, so it can be used on Ip,ipx,appletalk,osi and other transport protoco
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:
