useful tricks

Print maximum number of errors (output from EFX, data is on c0 under /scr/EFX/RRD/db):

 ls err*rrd | xargs -i rrdtool graph /tmp/test DEF:err_r={}:err_rec:MAX VDEF:max=err_r,MAXIMUM PRINT:max:"%6.2lf %S/s"|grep -v 0x0
 ls pack*rrd | xargs -i rrdtool graph /tmp/test DEF:err_r={}:rec:MAX VDEF:max=err_r,MAXIMUM PRINT:max:"%6.2lf %S/s"|grep -v 0x0

Create graph where error rate and packet rate are shown:
 montage -geometry 1000x600+0+0 pack_133-86400.png err_133-86400.png -tile 1x2 /tmp/test.png
