hello I did upgrade pmm 1.10 to 1.15 so old graph(scrap at 1.10) is not viewing. how I can view old scrap data? I did upgrade client 1.15 before server upgrade. but it’s too. ---

Hi [next1009](https://percona.vanillacommunities.com/profile/x/x/38295) I’m glad to see you on 1.15 now. You should not have lost any data, rather we did upgrade Prometheus in 1.13 so there are in fact two Prometheus deamons running in PMM Server. Prometheus has a feature called remote\_read so that any queries not satisfied in the first instance will be automatically fetched from the second instance. You can review the logs, please share anything of interest, they are /var/log/prometheus.log (Prom2) and /var/log/promtheus1.log (Prom1) ---

Hi [next1009](https://percona.vanillacommunities.com/profile/x/x/38295) Can you check also in log file /var/log/prometheus1.log for any entries, particularly whether the instance is restarting frequently? ---
