Tenable Import is slow

Tadz · ‎01-27-2022

Hi Team,

We have implemented Tenable.sc integration to ServiceNow.

Somehow the Import is quite slow.

I already tried setting the CMDB Asset Chunk Size to 500.

Somehow the retrieval improved but the importing process is slow.

Is there anything we can improve this? or is it normal for 300K plus records?

Thanks,

Tadz

Hi,

If number of records are more then you can expect a delay or performance issue.

As there might be some additional calls being made for each records to get related records.

There is possibility of some Business rules or automation logic is running in ServiceNow on creation of record.

These things can lead to slow performance.

Thanks,

Hi

have you tried disabling Vulnerability Calculators during the import?

This can speed up performance. You can then re-enable and re-apply calculators post import.

Thanks

Hi all, i have resolved the issue. It seems there is a custom business rule that was running doing some queries on cmdb_ci table. I just made an enhancement on the script and the job is now progressing okay.

Hi Tadz

I have just configured the tenable sc connector on my environment and im having issues and was wondering how your set up went.

The connector is healthy, were not importing from tenable into servicenow at the moment, but we are tryingt to configure a job that sends a small set of servicenow CI to tenable but having no luck.

the job query pulls back the relevant records but when we do the execute now for the job i can see it doesnt retrieve the records and cant figure it out. Was wondering if you had any similar issues?

Hi CandyDee,

In our current setup we are pulling data from Tenable to ServiceNow for vulnerabilities.

I'm not sure if we can send data from ServiceNow to Tenable.

My problem earlier is due to a BR that needs to be enhanced.

You can start a thread in community maybe someone might know 🙂

Thanks,
