M'nkhaniyi tikambirana pang'ono za kuyang'anira makina osungira a IBM Storwize ndi makina ena osungira omwe amathandiza ma protocol a CIM/WBEM. Kufunika kowunika kotereku sikuli kofanana; tilingalira izi ngati axiom. Tidzagwiritsa ntchito Zabbix ngati njira yowunikira.
M'matembenuzidwe aposachedwa a Zabbix, kampaniyo idayamba kuyang'ana kwambiri ma templates - ma templates adayamba kuwonekera pazoyang'anira ntchito, DBMS, Servers hardware (IMM/iBMC) kudzera pa IPMI. Kuyang'anira dongosolo losungirako likadali kunja kwa ma templates kunja kwa bokosi, kotero kuti muphatikize zambiri zokhudza momwe zinthu zilili ndi momwe zimagwirira ntchito zosungirako ku Zabbix, muyenera kugwiritsa ntchito ma templates okhazikika. Ndikubweretsa kwa inu imodzi mwama templates awa.
Choyamba, chiphunzitso chaching'ono.
Kuti mupeze mawonekedwe ndi ziwerengero za makina osungira a IBM Storwize, mutha kugwiritsa ntchito:
- Ndondomeko za CIM/WBEM;
- (yothandizidwa mu IBM Storwize kuyambira ndi pulogalamu ya 8.1.3);
- Misampha ya SNMP (misampha yochepa, palibe ziwerengero);
- Lumikizani kudzera pa SSH kenako patali .
Omwe ali ndi chidwi atha kuphunzira zambiri za njira zosiyanasiyana zowunikira m'magawo ofunikira a zolemba za ogulitsa, komanso mu chikalatacho. .
Tidzagwiritsa ntchito ma protocol a CIM/WBEM, omwe amatilola kupeza magawo ogwiritsira ntchito makina osungira popanda kusintha kwakukulu kwa mapulogalamu amitundu yosiyanasiyana yosungira. Ma protocol a CIM/WBEM amagwira ntchito motsatira . Storage Management Initiative - Mafotokozedwe amachokera pamiyezo yotseguka ΠΈ , wotsimikiza .
WBEM imayenda pamwamba pa protocol ya HTTP. Kudzera pa WBEM mutha kugwira ntchito osati ndi makina osungira okha, komanso ma HBA, masiwichi ndi malaibulale a matepi.
Malingana ndi ΠΈ , gawo lalikulu pakukhazikitsa kwa SMI ndi seva ya WBEM, yomwe imayang'anira zopempha za CIM-XML kuchokera kwa makasitomala a WBEM (kwa ife, kuchokera pakuwunika):
CIM ndi chitsanzo choyang'ana pa chinthu chotengera Chilankhulo Chogwirizana cha Umodzi (UML).
Zinthu zoyendetsedwa zimatanthauzidwa ngati makalasi a CIM omwe ali ndi katundu ndi njira zoyimira deta yoyendetsedwa ndi magwiridwe antchito.
Malingana ndi , kuti mupeze makina osungiramo zinthu kudzera pa CIM/WBEM, mungagwiritse ntchito PyWBEM - laibulale yotseguka yolembedwa ku Python, yomwe imapatsa opanga mapulogalamu ndi oyang'anira dongosolo kukhazikitsa ndondomeko ya CIM yopezera zinthu za CIM ndikuchita ntchito zosiyanasiyana ndi seva ya WBEM yomwe ikugwira ntchito. molingana ndi SMI-S kapena zina za CIM.
Kuti tigwirizane ndi seva ya WBEM timagwiritsa ntchito omanga kalasi :
conn = pywbem.WBEMConnection(server_uri, (self.login, self.password),
namespace, no_verification=True)
Uwu ndi kugwirizana kwenikweni, popeza CIM-XML/WBEM ikuyenda pamwamba pa HTTP, kugwirizana kwenikweni kumachitika pamene njira zimatchedwa chitsanzo cha gulu la WBEMConnection. Mogwirizana ndi IBM System Storage SAN Volume Controller ndi Storwize V7000 Best Practices and Performance Guidelines (Chitsanzo C-8, tsamba 412), tidzagwiritsa ntchito "root/ibm" ngati CIM namespace ya IBM Storwize yosungirako.
Chonde dziwani kuti kuti mutenge ziwerengero kudzera mu protocol ya CIM-XML/WBEM, muyenera kuphatikiza wogwiritsa ntchito pagulu loyenera lachitetezo. Kupanda kutero, poyankha mafunso a WBEM, zotulutsa zamtundu wamagulu sizikhala zopanda kanthu.
Kuti mupeze ziwerengero zosungirako, wogwiritsa ntchito yemwe womangayo amatchedwa , ayenera kukhala ndi RestrictedAdmin (yopezeka pa code_level> 7.8.0) kapena maufulu a Administrator (osavomerezeka pazifukwa zachitetezo).
Timalumikiza ku yosungirako kudzera pa SSH ndikuyang'ana manambala amagulu:
> lsusergrp
id name role remote
0 SecurityAdmin SecurityAdmin no
1 Administrator Administrator no
2 CopyOperator CopyOperator no
3 Service Service no
4 Monitor Monitor no
5 RestrictedAdmin RestrictedAdmin no
Onjezani wogwiritsa zabbix kugulu lomwe mukufuna:
> chuser -usergrp 5 zabbix
Kuphatikiza apo, molingana ndi IBM System Storage SAN Volume Controller ndi Storwize V7000 Best Practices and Performance Guidelines (p. 415), muyenera kuloleza kusonkhanitsa ziwerengero pa makina osungira. Chifukwa chake, kusonkhanitsa ziwerengero miniti iliyonse:
> startstats -interval 1
Kufufuza:
> lssystem | grep statistics
statistics_status on
statistics_frequency 1
Kuti mupeze makalasi onse osungira omwe alipo, muyenera kugwiritsa ntchito njira ya EnumerateClassNames().
Chitsanzo:
classnames = conn.EnumerateClassNames(namespace='root/ibm', DeepInheritance=True)
for classname in classnames:
print (classname)
Njirayi imagwiritsidwa ntchito kupeza zofunikira zamagawo osungira class WBEMConnection, kubwezera mndandanda wa zochitika .
Chitsanzo:
instances = conn.EnumerateInstances(classname,
namespace=nd_parameters['name_space'])
for instance in instances:
for prop_name, prop_value in instance.items():
print(' %s: %r' % (prop_name, prop_value))
M'makalasi ena omwe amakhala ndi zochitika zambiri, monga IBMTSSVC_StorageVolume, funso lathunthu lanthawi zonse limatha kukhala pang'onopang'ono. Ikhoza kupanga ma data akuluakulu omwe amayenera kukonzedwa ndi makina osungira, omwe amafalitsidwa pa intaneti ndikukonzedwa ndi script. Pali njira yochitira izi , zomwe zimatilola kuti tizingotenga zinthu zamakalasi zomwe zimatisangalatsa. Njira imeneyi ikuphatikizapo kugwiritsa ntchito chinenero chofanana ndi SQL, mwina CIM Query Language (DMTF:CQL) kapena WBEM Query Language (WQL), kuti mufufuze zinthu zosungirako za CIM:
request = 'SELECT Name FROM IBMTSSVC_StorageVolumeStatistics'
objects_perfs_cim = wbem_connection.ExecQuery('DMTF:CQL', request)
Kuti mudziwe makalasi omwe tikufunikira kuti tipeze magawo a zinthu zosungirako, werengani zolembazo, mwachitsanzo .
Chifukwa chake, kuti tipeze magawo (osati owerengera magwiridwe) a ma disks akuthupi (Disk Drives) tidzasankha Class IBMTSSVC_DiskDrive, kuti tipeze magawo a Volumes - Kalasi IBMTSSVC_StorageVolume, kuti mupeze magawo osiyanasiyana - Kalasi IBMTSSVC_Array, kupeza magawo a MDisks - Kalasi IBMTSSVC_Volume etc.
Kuti mugwiritse ntchito mukhoza kuwerenga (makamaka - ) ndi IBM System Storage SAN Volume Controller and Storwize V7000 Best Practices and Performance Guidelines (Chitsanzo C-11, tsamba 415).
Kuti mupeze ziwerengero zosungira Ma Volumes, muyenera kutchula IBMTSSVC_StorageVolumeStatistics ngati mtengo wa ClassName parameter. Katundu wa IBMTSSVC_StorageVolumeStatistics kalasi yofunikira pakutolera ziwerengero zitha kuwonedwa mu .
Komanso, pakuwunika magwiridwe antchito mutha kugwiritsa ntchito makalasi IBMTSSVC_BakendVolumeStatistics, IBMTSSVC_DiskDriveStatistics, IBMTSSVC_NodeStatistics.
Kulemba deta mu njira yowunikira tidzagwiritsa ntchito makinawo , yokhazikitsidwa mu python mu module . Tidzayika mawonekedwe a makalasi osungira ndi katundu wawo mu dikishonale mu mtundu wa JSON.
Timayika template ku seva ya Zabbix, onetsetsani kuti seva yowunikira ili ndi mwayi wopita kumalo osungirako zinthu kudzera pa WEB protocol (TCP/5989), ndikuyika mafayilo okonzekera, kuzindikira ndi kuyang'anira zolemba pa seva yowunikira. Kenako, onjezani kukhazikitsa kwa script kwa wokonza. Zotsatira zake: timapeza zinthu zosungira (zosanjikiza, ma disks akuthupi ndi enieni, zotsekera ndi zina zambiri), tumizani ku Zabbix zomwe zapezedwa, werengani mawonekedwe a magawo awo, werengani ziwerengero zamachitidwe (zowerengera zogwirira ntchito), tumizani zonsezi ku Zabbix yofanana. Zinthu za template yathu.
Zabbix template, python scripts, mapangidwe a makalasi osungira ndi katundu wawo, komanso zitsanzo za mafayilo osinthika, mukhoza .
