You are getting below error message while opening the transaction code ST06.
Timeliness check of snapshot data not possible (no collector timestamp)
Solution
The solution referred to this SAP Note, 3042761 – ST06 error “Timeliness check of snapshot data not possible ( no collector timestamp )” for Application Server
- Check the dev_coll trace file (/usr/sap/tmp or AL11 DIR_PERF). The trace may end with “Got SIGSEGV”. In that case follow through the steps of KBA note 2763589 – Saposcol is not running – Got SIGSEGV. Note: Please remember to delete coll.put before restarting sap host agent and saposcol.
- If “Got SIGSEGV” from step 1 is not the issue, then check the [SID]ADM user is assigned to group sapsys:
Run the following command under user root:
/usr/sap/hostctrl/exe/saposcol -s
Run the same command under user [sid]adm
If the command succeeds under user root but fails under user [sid]adm then the problem is that user [sid]adm is not in group sapsys. In that case the ABAP processes (running under user [sid]adm) do not have permissions to read the data from saposcol and the transaction ST06 cannot read the data from it. Assign user [sid]adm to the group sapsys and restart the ABAP instances.
