Abstract
The invention provides a server monitoring and management method based on a Nagios and a BMC. According to the method, interactive access of the Nagios to server out-band monitoring information is achieved, paths for server monitoring and management are expanded, and availability of a server is improved. The method mainly includes the steps of server node installation and Nagios configuration, BMC-based Nagios extensive plug-in obtaining, python script compiling based on an IPMI protocol, hardware communication interface achievement between the Nagios and the BMC, client remote monitoring and management through the server and the like. By means of information interaction between a Nagios tool and a BMC controller, a BMC-based function plug-in is expanded on the basis of an original in-band monitoring and management system based on the Nagios, Nagios-based information acquisition is increased on the basis of an original out-band monitoring and management system based on the BMC, and server system availability is improved through key information interaction of the two systems.
Description
technical field
the present invention designs a kind of server technology, specifically a kind of server monitoring management method based on Nagios and BMC.
Background technology
The various aspects server of society all plays an important role, and no matter is national defence, science and technology, banking and insurance business, or bank, the energy, state enterprise, and there is the existence of server nearly all aspect.For ensureing the stable operation of above-mentioned work in every, if effectively server is carried out to monitoring management work has just become crucial prerequisite in real time.Instrument for server monitoring is a variety of, such as Open-Source Tools Ganglia, Nagios, Zabbix, and professional tool Pingdom, interSeptorPro, Nimsoft etc., these instruments can monitor the information of server every aspect, from running time, performance to safety, even arrive the residing physical environment index of server.Ganglia, for measuring thousands of server nodes, provides static system data and important performance metric data, is particularly useful for cloud computing system; Nagios is a kind of server level and network monitoring program, and it detects main frame and service, can reminding user in the time of abnormal generation and releasing.Zabbix is that a distributed system that provides based on WEB interface monitors and network monitoring function source solution; Pingdom can monitor running time and overall performance, and form and the chart read are convenient in generation, interSeptor is Ethernet data center and frame supervisory control system, it can monitoring room and the environmental aspect of frame, once occur that other situations that the system failure maybe may jeopardize business continuance will send early warning; NMS can monitoring server core resource, can manage remote process and service concentratedly.Substantially can recognize by these instruments what problem may appear in server, and solved them before problem occurs.Single Open-Source Tools function is limited, need multiple types of tools combination competence exertion effectively to act on, and cannot obtain professional technical support, but can freely obtain, and enterprise-level professional tool is powerful and be furnished with professional technique support, but price is but very expensive.
Adopt in recent years Open-Source Tools to monitor and the solution that has just become main flow of safeguarding server system, but because these monitoring tools of increasing income respectively have feature and emphasis, be difficult to all instruments all to install in actual monitored and maintenance process, allow to installation system administrative staff and be also difficult to energy and process the working condition of all instruments, so just brought very large problem to monitoring management.Therefore, how effectively integration Open-Source Tools solution, simplify monitoring management flow process, the problem of again can be all-sidedly and accurately server under server system and even server cluster system occasion being carried out to monitoring management and just become to need badly solution.
Summary of the invention
How effectively the integration Open-Source Tools solution for, simplify monitoring management flow process, can carry out monitoring management to server system all-sidedly and accurately again, the present invention proposes a kind of server monitoring management method based on Nagios and BMC.
The present invention includes: server node installs and configuration Nagios, realize, write between the realization of python script, Nagios and BMC the parts such as hardware communication interface realization, server remote monitoring and administration client based on IPMI agreement towards the Nagios expansion plugin of BMC.
Wherein, server node is installed and configuration Nagios, need to and be managed in management and on server node, all installs and carry out necessary configuration, and Nagios can normally be worked, and management node can obtain the monitoring management information that is managed node by Nagios;
Wherein, towards the Nagios expansion plugin of BMC, main purpose is to set up interactive interface file between Nagios and IPMI specification, the expansion plugin based on C language compilation nagios_ipmi_monitor can be downloaded in Nagios official website, the present invention utilizes the better script python of professional platform independence to realize, and has increased on the original basis the interface document that obtains Nagios monitor message towards BMC.
1. Nagios obtains BMC information monitor_nagios_to_bmc_plugins plug-in unit group and mainly comprises that power supply, fan, voltage, temperature sensor state obtain, and the operation such as managing power consumption, log information derivation;
monitor_bmc_fan.py、monitor_bmc_temp.py、
monitor_bmc_psu.py、monitor_bmc_psu_control.py、
monitor_bmc_voltage.py、monitor_bmc_logs.py；
2. BMC obtains Nagios information get_nagios_to_bmc_plugins plug-in unit group and mainly comprises the state informations such as cpu busy percentage, memory usage, hard disk utilance, process status, network performance index:
get_nagios_cpu_usgage.py、get_nagios_mem_usgage.py、
get_nagios_ps_status.py、get_nagios_hdd_status.py、
get_nagios_net_status.py;
Wherein, between Nagios and BMC, hardware communication interface is the KCS interface based on LPC agreement, is applicable to the CPU of Intel X86 platform;
Wherein, server remote monitoring and administration client is mounted in the Webserver of BMC, and user can sign-on access by WebBrowser;
Wherein, server remote monitoring and administration client deployment is held at BMC, and it possesses basic out of band supervision management function, i.e. assets information detection, Long-distance Control maintenance, system log message, event alarm etc., the crucial in-band information providing based on Nagios in addition, has increased in-band information monitoring;
Wherein, the present invention is by the information interaction of Nagios instrument and BMC controller, in original band based on Nagios, on monitoring management system basis, expand the feature card towards BMC, on original out of band supervision management system basis based on BMC, increased the acquisition of information towards Nagios;
The invention has the beneficial effects as follows:
Without specific Agent end is installed at client server end, only need on the Nagios monitoring management instrument that client has installed, to the expansion plugin based on standard I PMI agreement of BMC, so ensure that customer information fail safe has also reduced the difficulty of system maintenance by installed surface.
Make client on original method for managing and monitoring, increase information standby mutually, no matter from being with interior system or can obtaining system core information from band external system, increased fail safe and the availability of system operation.
Effectively integration Open-Source Tools solution, simplifies monitoring management flow process, can be that under system occasion, server carries out monitoring management to server system all-sidedly and accurately again.
