This article mainly introduces how the script realizes the number of pg in osd, which has certain reference value. Interested friends can refer to it. I hope you will have a lot of gains after reading this article. Let Xiaobian take you to understand it together.

The script code is as follows: ceph pg dump| awk ' /^pg_stat/ { col=1; while($col!= "up") {col++}; col++ } /^[0-9a-f]+. [0-9a-f]+/ { match($0,/^[0-9a-f]+/); pool=substr($0, RSTART, RLENGTH); poollist[pool]=0; up=$col; i=0; RSTART=0; RLENGTH=0; delete osds; while(match(up,/[0-9]+/)>0) { osds[++i]=substr(up,RSTART,RLENGTH); up = substr(up, RSTART+RLENGTH) } for(i in osds) {array[osds[i],pool]++; osdlist[osds[i]];} } END { printf("\n"); printf("pool :\t"); for (i in poollist) printf("%s\t",i); printf("| SUM \n"); for (i in poollist) printf("--------"); printf("----------------\n"); for (i in osdlist) { printf("osd.% i\t", i); sum=0; for (j in poollist) { printf("%i\t", array[i,j]); sum+=array[i,j]; poollist[j]+=array[i,j] }; printf("| %i\n",sum) } for (i in poollist) printf("--------"); printf("----------------\n"); printf("SUM :\t"); for (i in poollist) printf("%s\t",poollist[i]); printf("|\n"); }'

Thank you for reading this article carefully. I hope that the article "How to achieve statistics on pg number in osd" shared by Xiaobian will be helpful to everyone. At the same time, I hope that everyone will support you a lot and pay attention to the industry information channel. More relevant knowledge is waiting for you to learn!
