Kwụpụ 1: Wụnye Zabbix-Agent na Linux
Iji nyochaa akpa Docker na sava dịpụrụ adịpụ, ịkwesịrị ịwụnye onye nnọchi anyaZabbix, nke bụ onye na-ahụ maka nleba anya nke etinyere na oghere ebumnuche iji nyochaa usoro metrik na ngwa ndị ọzọ.
Nke mbụ, ịkwesịrị ịwụnye ebe nchekwa Zabbix na oghere Docker.

Kwụpụ 2: Hazie Zabbix-Agent na Linux
Site na ndabara, onye ọrụ Zabbix ka atọrọ ibuga metrik gaa na sava Zabbix n'otu nnabata etinyere ya. Ebe ebumnobi anyị bụ inyocha arịa docker na sava dịpụrụ adịpụ, achọrọ ụfọdụ nhazi ndị ọzọ.
Ya mere, nweta faịlụ nhazi onye ọrụ Zabbix.
$ sudo vim /etc/zabbix/zabbix_agent2.conf
Faịlụ nhazi ahụ nwere ntọala na-akọwapụta adreesị ebe ezigara metrics, ọdụ ụgbọ mmiri ejiri maka njikọ yana ọtụtụ ihe ndị ọzọ. Maka ọtụtụ akụkụ, ntọala ndabara ga-arụ ọrụ nke ọma.
Iji hazie onye nnọchi anya Zabbix ka iziga metrik na sava Zabbix, chọta ntuziaka nke ahaziri iji bubata metrik na adreesị loopback, ma ọ bụ tinye naanị, otu sistemụ nnabata ahụ.
Server=127.0.0.1
Tọọ adreesị ka ọ gosipụta adreesị nkesa Zabbix

Na mgbakwunye, gaa na ngalaba 'Nleba anya na-arụ ọrụ' wee gbanwee ntuziaka iji rụtụ aka na adreesị IP nke sava Zabbix.

Jide n'aka na igbanwekwara aha nnabata nke ihe nkesa Docker otu a. Aha nnabata nke ihe nkesa Docker m bụ Ubuntu20.
Hostname=Ubuntu20
Wee chekwaa mgbanwe ndị ahụ wee pụọ na faịlụ nhazi Zabbix.
Maka onye ọrụ Zabbix ka ọ lekwasị anya na arịa Docker, ịkwesịrị ịgbakwunye onye ọrụ Zabbix, nke arụnyere na ndabara, na otu docker.
$ sudo usermod -aG docker zabbix
Iji tinye mgbanwe ndị emere na faịlụ nhazi, malitegharịa ọrụ Zabbix-agent ma mee ka ọ malite na mmalite usoro.
$ sudo systemctl restart zabbix-agent2 $ sudo systemctl enable zabbix-agent2
Kwenye ọkwa na-agba ọsọ nke onye nnọchi anya Zabbix dị ka ndị a.
$ sudo systemctl status zabbix-agent2
Onye ọrụ Zabbix na-ege ntị na ọdụ ụgbọ mmiri 10050. Ọ bụrụ na ị nwere firewalld na-agba ọsọ, tụlee imepe ọdụ ụgbọ mmiri dị ka ndị a.
----------- On UFW Firewall ----------- $ sudo ufw allow 10050/tcp $ sudo ufw reload ----------- On Firewalld ----------- $ sudo firewall-cmd --add-port=10050/tcp --permanent $ sudo firewall-cmd --reload
Nnukwu! Anyị nọ ugbu a n'ọkara akara. Onye ọrụ Zabbix nwere ike ibuga metrics akpa Docker na sava Zabbix.
Na nzọụkwụ na-esote, anyị ga-agbakwunye ihe nkesa Docker na interface weebụ Zabbix ma nyochaa akpa Docker.
Kwụpụ 3: Tinye Docker na Zabbix Server maka nlekota oru
Iji nyochaa onye ọbịa dịpụrụ adịpụ, ịkwesịrị ịgbakwunye ya na dashboard nke sava Zabbix site na ihe nchọgharị. Zabbix na-enye ndebiri ndebiri maka ọrụ na ngwa dị iche iche. Anyị ga-ejikọta template kwesịrị ekwesị na onye ọrụ Docker iji nyochaa arịa kpọmkwem. Mana nke mbụ, nweta ibe nbanye nke sava Zabbix.

Ozugbo ị banyere, gaa n'akụkụ aka nri wee pịa 'Configuration' wee 'Ndị ọbịa'.
N'akụkụ aka nri aka nri, pịa 'Mepụta onye ọbịa'.
Dejupụta nkọwa nke ihe nkesa Docker dị ka aha nnabata & aha a na-ahụ anya. Maka otu, Pịnye na 'Docker Groups' (onye ọ bụla ga-ejikọta ya na otu).
N'okpuru akara 'Interfaces' pịa 'Tinye' na menu nke gosipụtara họrọ 'Agent'.
Na-esote, dejupụta adreesị IP nke ihe nkesa Docker wee hụ na edobere ọdụ ụgbọ mmiri na 10050.
Na-esote, pịa taabụ Templates, na na ngalaba 'njikọ ọhụrụ ndebiri', kọwaa 'Docker site Zabbix agent 2'. Wee pịa bọtịnụ 'Tinye'.
Mgbe ịpịrị bọtịnụ Tinye, a ga-agbakwunye onye ọbịa Docker dịpụrụ adịpụ na-akpaghị aka dị ka egosiri.
N'oge a, ihe nkesa Zabbix na-enyocha ihe nkesa Docker gị ugbu a. N'ọzọ na-esote, anyị ga-ebunye akpa wee chọpụta nke metrik enwere ike nyochaa.
Kwụpụ 4: Nyochaa Metrics Docker na nlekota oru Zabbix
Iji malite nlekota Docker metrics, anyị ga-ebupụta akpa ule. Yabụ, laghachi na sava Docker gị wee malite akpa.
N'ihe atụ a, anyị ga-adọta ihe oyiyi akpa Ubuntu wee mepụta akpa a na-akpọ docker_test_container. Anyị ga-enweta ohere shei site na iji -it nhọrọ. Iwu niile maka arụmọrụ bụ ndị a.
$ sudo docker run --name docker_test_container -it ubuntu bash
Ị nwere ike ịnwale ihe dị oke egwu dị ka ịwụnye ngwugwu ngwanrọ dị ka Apache ma ọ bụ MariaDB iji mepụta ụfọdụ metrik dị ka iji CPU na okporo ụzọ netwọk.
Ugbu a laghachi na dashboard sava Zabbix. Pịa na 'Nleba anya' wee 'Ndị ọbịa'. Pịa aha ihe nkesa Docker gị yana na nhọrọ menu gosipụtara, họrọ 'data kacha ọhụrụ'.
Mgbe nkeji ole na ole nke ibugharị akpa ahụ gasịrị, ihe nkesa Zabbix ga-achọpụta akpa ahụ wee malite ịmepụta ụfọdụ ọnụ ọgụgụ.
Ị nwekwara ike ịlele eserese nke metrik akpa dị iche iche site na ịpị nhọrọ 'graphs' nke sava Docker na ibe 'Ndị ọbịa'. N'okpuru, ị nwere ike ịhụ metrik ojiji CPU & ebe nchekwa.
Iji mee ka mkpọka akpa ahụ dị, anyị ga-apụ na akpa ahụ na-atụghị anya ya site n'itinye iwu dị n'okpuru na shei akpa ahụ.
# exit 2
Nke a pụtara na anyị ejirila koodu njehie 2 kwụsịchaa akpa ahụ. A na-edekọ nke a n'ime metadata nke akpa ahụ. Iji lelee njikere, gaa n'akụkụ aka ekpe wee pịa 'Nleba anya' wee 'Dashboard'.
E gosipụtara ọkwa ahụ n'okpuru.
Iji mezie njehie ahụ, naanị malite akpa ahụ ọzọ.
$ sudo docker start docker_test_container
Nke a na-edugakwa anyị na njedebe nke ntuziaka a. Anyị ejegharịla gị site na usoro nzọụkwụ nke otu ị ga-esi nyochaa arịa Docker site na iji ngwaọrụ nlekota Zabbix.
