問題描述：An error occurred: Error while processing samples:Mismatch between expected number of columns:17 and columns in CSV file:14, check your jmeter.save.saveservice.* configuration or check line is complete
最近在穩定性測試時，我使用了nohup掛載jmx進行測試24h
nohup jmeter -n -t chenbean.jmx -l 100th24h.csv -e -o 100th24h > 24hnohup.csv 2>&1 &
但是第二天我上去看發現我自動生成 報告失敗了，所以我打算手動根據已有的csv生成html報告試下：
jmeter -g 100th24h.csv -e -o resultdir
結果還是報錯：
An error occurred: Error while processing samples:Mismatch between expected number of columns:17 and columns in CSV file:14, check your jmeter.save.saveservice.* configuration or check line is complete
意思是我要求有17列解析，卻發現你一行只有14列：
我就vi 進入csv最后查看：結果如下
1589930374049,1220,Java Request,0,success,Thread Group 1-45,text,true,,47231,0,55,55,null,0,0,0
1589930374050,1220,Java Request,0,success,Thread Group 1-25,text,true,,47213,0,55,55,null,0,0,0
1589930373938,1439,Java Request,0,success,Thread Group 1-54,text,true,,47237,0,53,53,null,0,0,0
1589930374031,1349,Java Request,0,success,Thread Group 1-41,text,true,,47219,0,52,52,null,0,0,0
1589930374238,1146,Java Request,0,success,Thread Group 1-44,text,true,,47223,0,51,51,null,0,0,0
1589930374391,986,Java Request,0,success,Thread Group 1-7,text,true,,47255,0,53,53,nul
明顯最有一行null開始就寫入有問題了導致后幾列都沒寫入，至此破案了刪掉最后一行重新執行 jmeter -g 100th24h.csv -e -o resultdir
問題解決
