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