नागिओस में विंडोज़ होस्ट जोड़ना:एक चरण-दर-चरण मार्गदर्शिका

1. RHEL/CentOS 6.x/5.x और Fedora 19/18/17 पर नागियोस 4.0.1 कैसे स्थापित करें
2. Nagios मॉनिटरिंग सर्वर में Linux होस्ट जोड़ें

1. Windows मशीन पर NSClient++ ऐडऑन इंस्टॉल करें।
2. विंडोज मशीन की निगरानी के लिए नागियोस सर्वर कॉन्फ़िगर करें।
3. Windows मशीन मॉनिटरिंग के लिए नई होस्ट और सेवा परिभाषाएँ जोड़ें।
4. नागियोस सेवा को पुनः आरंभ करें।

1. ए check_nt कमांड परिभाषा पहले ही command.cfg में जोड़ दी गई है फ़ाइल. इस परिभाषा कमांड का उपयोग check_nt द्वारा किया जाता है विंडोज़ सेवाओं की निगरानी के लिए प्लगइन।
2. एक विंडोज़-सर्वर होस्ट टेम्पलेट templates.cfg में पहले ही बनाया जा चुका है फ़ाइल. यह टेम्प्लेट आपको नई विंडोज़ होस्ट परिभाषाएँ जोड़ने की अनुमति देता है।
