5    #
6    # Usage: sap.monitor [-[hH] ashost only/ignore] [-[sS] sysnr only/ignore]
7    #
8    # e.g.  sap.monitor -s 20       will scan only hosts with sysnr == 20
9    #       sap.monitor -S 20       will scan only hosts with sysnr != 20
10    
11    # configuration file in /usr/local/etc/sap-mon.conf describes which
12    # hosts (ashost) and systems (sysnr) you want to check.
13    #
14    # format of line is:
15    #
16    # ashost [tab|space] sysnr # optional comment
17    #
18    # you can spacify host as hostname (sap01) or with sap routers in-between
19    # to test routers too (/H/saprtr/H/sap01)
