3. Issues and Mitigation
| Issue Description | Mitigation Description |
|---|---|
| High availability of central operational tools is needed. | GOCDB: dynamic loadbalancing DNS setup is provided for the address goc.egi.eu. Secondary instance in Fraunhofer institute is still being deployed. Delay is caused by the development and deployment of the new GOCDB version. |
| Monitoring of underperforming sites. | COD team has proposed monitoring of availability and reliability of sites. In case of decreased A/R alarm would be raised against the site. Such approach would enable sites to correct A/R figures before the end of the month and stay within OLA thresholds. Discussions have started on defining implementation details. |
