After migration to zabbix-agent2 we are facing old web.page.get issue, already fixed for zabbix_agentd: ZBX-9892. If chunked transfer encoding is enabled on the webserver, web.page.get gets response with chunk size data.
Steps to reproduce:
zabbix_agentd: (works correctly)
zabbix_agentd -t 'web.page.get["localhost","ping","8085"]'
web.page.get["localhost","ping","8085"] [t|HTTP/1.1 200 OK Server: nginx Date: Thu, 26 May 2022 16:05:08 GMT Content-Type: text/plain;charset=UTF-8 Transfer-Encoding: chunked Connection: keep-alive Vary: Accept-Encoding Expires: Thu, 01 Jan 1970 00:00:00 GMT Cache-Control: no-cache, no-store, must-revalidate, max-age=0 Content-Encoding: gzip pong]
zabbix_agent2: (does not work correctly)
zabbix_agent2 -t 'web.page.get["localhost","ping","8085"]'
web.page.get["localhost","ping","8085"] [s|HTTP/1.1 200 OK Connection: close Transfer-Encoding: chunked Cache-Control: no-cache, no-store, must-revalidate, max-age=0 Content-Type: text/plain;charset=UTF-8 Date: Thu, 26 May 2022 16:06:45 GMT Expires: Thu, 01 Jan 1970 00:00:00 GMT Server: nginx Vary: Accept-Encoding 4 pong 0]
After disabling chunked transfer encoding on nginx with chunked_transfer_encoding off; web.page.get works correctly.
zabbix_agent2 -t 'web.page.get["localhost","ping","8085"]'
web.page.get["localhost","ping","8085"] [s|HTTP/1.1 200 OK Connection: close Cache-Control: no-cache, no-store, must-revalidate, max-age=0 Content-Type: text/plain;charset=UTF-8 Date: Thu, 26 May 2022 16:12:10 GMT Expires: Thu, 01 Jan 1970 00:00:00 GMT Server: nginx Vary: Accept-Encoding pong]
You can also test with zabbix.com domain as zabbix_agent2 -t web.page.get[www.zabbix.com]/]
