2 # File: sap.monitor

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)
